+```c
+#include "stdlib/stats/base/smskmax.h"
+```
+
+#### stdlib_strided_smskmax( N, \*X, strideX, \*Mask, strideMask )
+
+Computes the maximum value of a single-precision floating-point strided array according to a mask.
+
+```c
+#include
+
+const float x[] = { 1.0f, -2.0f, 2.0f };
+const uint8_t mask[] = { 0, 1, 0 };
+
+float v = stdlib_strided_smskmax( 3, x, 1, mask, 1 );
+// returns 2.0f
+```
+
+The function accepts the following arguments:
+
+- **N**: `[in] CBLAS_INT` number of indexed elements.
+- **X**: `[in] float*` input array.
+- **strideX**: `[in] CBLAS_INT` stride length for `X`.
+- **Mask**: `[in] uint8_t*` mask array. 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**: `[in] CBLAS_INT` stride length for `Mask`.
