+# selmax
+
+> Calculate the maximum value of a strided array by selecting elements according to a mask.
+
+<section class="intro">
+
+</section>
+
+<!-- /.intro -->
+
+<section class="usage">
+
+## Usage
+
+```javascript
+var selmax = require( '@stdlib/stats/strided/selmax' );
+```
+
+#### selmax( N, x, strideX, mask, strideMask )
+
+Computes the maximum value of a strided array by selecting elements according to a mask.
+
+```javascript
+var x = [ 1.0, -2.0, 4.0, 2.0 ];
+var mask = [ 1, 1, 0, 1 ];
+
+var v = selmax( x.length, x, 1, mask, 1 );
+// returns 2.0
+```
+
+The function has the following parameters:
+
+-   **N**: number of indexed elements.
+-   **x**: input [`Array`][mdn-array] or [`typed array`][mdn-typed-array].
+-   **strideX**: stride length for `x`.
+-   **mask**: mask [`Array`][mdn-array] or [`typed array`][mdn-typed-array]. If a `mask` array element is `true`, the corresponding element in `x` is considered valid and **included** in computation. If a `mask` array element is `false`, 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 maximum value of every other element in `x`,
+
+```javascript
+var x = [ 1.0, 2.0, -7.0, -2.0, 4.0, 3.0, 5.0, 6.0 ];
+var mask = [ 1, 1, 1, 1, 1, 1, 0, 0 ];
+
+var v = selmax( 4, x, 2, mask, 2 );
+// returns 4.0
+```
+
+Note that indexing is relative to the first index. To introduce offsets, use [`typed array`][mdn-typed-array] views.
+
+<!-- eslint-disable stdlib/capitalized-comments -->
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+var BooleanArray = require( '@stdlib/array/bool' );
+
+var x0 = new Float64Array( [ 2.0, 1.0, -2.0, -2.0, 3.0, 4.0, 5.0, 6.0 ] );
+var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 );
+
+var mask0 = new BooleanArray([
+    true, true, true, true, true, true, false, false
+]);
+var mask1 = new BooleanArray( mask0.buffer, mask0.BYTES_PER_ELEMENT*1 );
+
+var v = selmax( 4, x1, 2, mask1, 2 );
+// returns 4.0
+```
+
+#### selmax.ndarray( N, x, strideX, offsetX, mask, strideMask, offsetMask )
+
+Computes the maximum value of a strided array by selecting elements according to a mask and using alternative indexing semantics.
+
+```javascript
+var x = [ 1.0, -2.0, 4.0, 2.0 ];
+var mask = [ 1, 1, 0, 1 ];
+
+var v = selmax.ndarray( x.length, x, 1, 0, mask, 1, 0 );
+// returns 2.0
+```
+
+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 maximum value for every other value in `x` starting from the second value
+
+```javascript
+var x = [ 2.0, 1.0, -2.0, -2.0, 3.0, 4.0, 5.0, 6.0 ];
+var mask = [ 1, 1, 1, 1, 1, 1, 0, 0 ];
+
+var v = selmax.ndarray( 4, x, 2, 1, mask, 2, 1 );
+// returns 4.0
+```
+

+
+<!-- /.usage -->
+
+<section class="notes">
+
+## Notes
+
+-   If `N <= 0`, both functions return `NaN`.
+-   Both functions support array-like objects having getter and setter accessors for array element access (e.g., [`@stdlib/array/base/accessor`][@stdlib/array/base/accessor]).
