+# smskmidrange
+
+> Calculate the [mid-range][mid-range] of a single-precision floating-point strided array according to a mask.
+
+
+
+The [**mid-range**][mid-range], or **mid-extreme**, is the arithmetic mean of the maximum and minimum values in a data set. The measure is the midpoint of the range and a measure of central tendency.
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var smskmidrange = require( '@stdlib/stats/strided/smskmidrange' );
+```
+
+#### smskmidrange( N, x, strideX, mask, strideMask )
+
+Computes the [mid-range][mid-range] of a single-precision floating-point strided array according to a mask.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+var Uint8Array = require( '@stdlib/array/uint8' );
+
+var x = new Float32Array( [ 1.0, -2.0, 4.0, 2.0 ] );
+var mask = new Uint8Array( [ 0, 0, 1, 0 ] );
+
+var v = smskmidrange( x.length, x, 1, mask, 1 );
+// returns 0.0
+```
+
+The function has the following parameters:
+
+- **N**: number of indexed elements.
+- **x**: input [`Float32Array`][@stdlib/array/float32].
+- **strideX**: stride length for `x`.
+- **mask**: mask [`Uint8Array`][@stdlib/array/uint8]. If a `mask` array element is `0`, the corresponding element in `x` is considered valid and **included** in computation. If a `mask` array element is `1`, the corresponding element in `x` is considered invalid/missing and **excluded** from computation.
+- **strideMask**: stride length for `mask`.
+
+The `N` and stride parameters determine which elements in the strided arrays are accessed at runtime. For example, to compute the [mid-range][mid-range] of every other element in `x`,
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+var Uint8Array = require( '@stdlib/array/uint8' );
+
+var x = new Float32Array( [ 1.0, 2.0, -7.0, -2.0, 4.0, 3.0, 5.0, 6.0 ] );
+var mask = new Uint8Array( [ 0, 0, 0, 0, 0, 0, 1, 1 ] );
+
+var v = smskmidrange( 4, x, 2, mask, 2 );
+// returns -1.5
+```
+
+Note that indexing is relative to the first index. To introduce offsets, use [`typed array`][mdn-typed-array] views.
+
+
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+var Uint8Array = require( '@stdlib/array/uint8' );
+
+var x0 = new Float32Array( [ 2.0, 1.0, -2.0, -2.0, 3.0, 4.0, 5.0, 6.0 ] );
+var x1 = new Float32Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+var mask0 = new Uint8Array( [ 0, 0, 0, 0, 0, 0, 1, 1 ] );
+var mask1 = new Uint8Array( mask0.buffer, mask0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+var v = smskmidrange( 4, x1, 2, mask1, 2 );
+// returns 1.0
+```
+
+#### smskmidrange.ndarray( N, x, strideX, offsetX, mask, strideMask, offsetMask )
+
+Computes the [mid-range][mid-range] of a single-precision floating-point strided array according to a mask and using alternative indexing semantics.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+var Uint8Array = require( '@stdlib/array/uint8' );
+
+var x = new Float32Array( [ 1.0, -2.0, 4.0, 2.0 ] );
+var mask = new Uint8Array( [ 0, 0, 1, 0 ] );
+
+var v = smskmidrange.ndarray( x.length, x, 1, 0, mask, 1, 0 );
+// returns 0.0
+```
+
+The function has the following additional parameters:
+
+- **offsetX**: starting index for `x`.
+- **offsetMask**: starting index for `mask`.
+
+While [`typed array`][mdn-typed-array] views mandate a view offset based on the underlying buffer, the offset parameters support indexing semantics based on starting indices. For example, to calculate the [mid-range][mid-range] for every other element in `x` starting from the second element
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+var Uint8Array = require( '@stdlib/array/uint8' );
+
+var x = new Float32Array( [ 2.0, 1.0, -2.0, -2.0, 3.0, 4.0, 5.0, 6.0 ] );
+var mask = new Uint8Array( [ 0, 0, 0, 0, 0, 0, 1, 1 ] );
+
+var v = smskmidrange.ndarray( 4, x, 2, 1, mask, 2, 1 );
+// returns 1.0
+```
+
+
+
+
+
+
+
+## Notes
+
+- If `N <= 0`, both functions return `NaN`.
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var uniform = require( '@stdlib/random/array/uniform' );
+var bernoulli = require( '@stdlib/random/array/bernoulli' );
+var smskmidrange = require( '@stdlib/stats/strided/smskmidrange' );
+
+var x = uniform( 10, -50.0, 50.0, {
+ 'dtype': 'float32'
+});
+console.log( x );
+
+var mask = bernoulli( x.length, 0.2, {
+ 'dtype': 'uint8'
+});
+console.log( mask );
+
+var v = smskmidrange( x.length, x, 1, mask, 1 );
+console.log( v );
+```

+{{alias}}( N, x, strideX, mask, strideMask )
+ Computes the mid-range of a single-precision floating-point strided array
+ according to a mask.
+
+ The `N` and stride parameters determine which elements in the strided arrays
+ are accessed at runtime.
+
+ Indexing is relative to the first index. To introduce offsets, use typed
+ array views.
+
+ If a `mask` array element is `0`, the corresponding element in `x` is
+ considered valid and included in computation.
+
+ If a `mask` array element is `1`, the corresponding element in `x` is
+ considered invalid/missing and excluded from computation.
+
+ If `N <= 0`, the function returns `NaN`.
+
+ Parameters
+ ----------
+ N: integer
+ Number of indexed elements.
+
+ x: Float32Array
+ Input array.
+
+ strideX: integer
+ Stride length for `x`.
+
+ mask: Uint8Array
+ Mask array.
+
+ strideMask: integer
+ Stride length for `mask`.
+
+ Returns
+ -------
+ out: number
+ Mid-range.
+
+ Examples
+ --------
+ // Standard Usage:
+ > var x = new {{alias:@stdlib/array/float32}}( [ 1.0, -2.0, 4.0, 2.0 ] );
+ > var mask = new {{alias:@stdlib/array/uint8}}( [ 0, 0, 1, 0 ] );
+ > {{alias}}( x.length, x, 1, mask, 1 )
+ 0.0
+
+ // Using `N` and stride parameters:
+ > x = new {{alias:@stdlib/array/float32}}( [ -2.0, 1.0, 1.0, -5.0, 2.0, -1.0, 4.0 ] );
+ > mask = new {{alias:@stdlib/array/uint8}}( [ 0, 0, 0, 0, 0, 0, 1 ] );
+ > {{alias}}( 3, x, 2, mask, 2 )
+ 0.0
+
+ // Using view offsets:
+ > var x0 = new {{alias:@stdlib/array/float32}}( [ 1.0, -2.0, 3.0, 2.0, 5.0, -1.0, 4.0 ] );

+
+
+{{alias}}.ndarray( N, x, strideX, offsetX, mask, strideMask, offsetMask )
+ Computes the mid-range of a single-precision floating-point strided array
+ according to a mask and using alternative indexing semantics.
+
+ While typed array views mandate a view offset based on the underlying
+ buffer, offset parameters support indexing semantics based on starting
+ indices.
+
+ Parameters
+ ----------
+ N: integer
+ Number of indexed elements.
+
+ x: Float32Array
+ Input array.
+
+ strideX: integer
+ Stride length for `x`.
+
+ offsetX: integer
+ Starting index for `x`.
+
+ mask: Uint8Array
+ Mask array.
+
+ strideMask: integer
+ Stride length for `mask`.
+
+ offsetMask: integer
+ Starting index for `mask`.
+
+ Returns
+ -------
+ out: number
+ Mid-range.
+
+ Examples
+ --------
+ // Standard Usage:
+ > var x = new {{alias:@stdlib/array/float32}}( [ 1.0, -2.0, 2.0, 4.0 ] );
+ > var mask = new {{alias:@stdlib/array/uint8}}( [ 0, 0, 0, 1 ] );
+ > {{alias}}.ndarray( x.length, x, 1, 0, mask, 1, 0 )
