+### Usage
+
+```c
+#include "stdlib/blas/base/isamax.h"
+```
+
+#### c_isamax( N, \*X, strideX )
+
+Finds the index of the first element having the maximum absolute value.
+
+```c
+const float x[] = { 4.0f, 2.0f, -3.0f, 5.0f, -1.0f };
+
+int idx = c_isamax( 5, x, 1 );
+// returns 3
+```
+
+The function accepts the following arguments:
+
+- **N**: `[in] CBLAS_INT` number of indexed elements.
+- **X**: `[in] float*` first input array.
+- **strideX**: `[in] CBLAS_INT` index increment for `X`.
+
+```c
+CBLAS_INT c_isamax( const CBLAS_INT N, const double *X, const CBLAS_INT strideX );
+```
+
+#### c_isamax_ndarray( N, \*X, strideX, offsetX )
+
+Finds the index of the first element having the maximum absolute value using alternative indexing semantics.
+
+```c
+const float x[] = { 4.0f, 2.0f, -3.0f, 5.0f, -1.0f };
+
+int idx = c_isamax_ndarray( 5, x, 1, 0 );
+// returns 3
+```
+
+The function accepts the following arguments:
+
+- **N**: `[in] CBLAS_INT` number of indexed elements.
+- **X**: `[in] float*` first input array.
+- **strideX**: `[in] CBLAS_INT` index increment for `X`.
+- **offsetX**: `[in] CBLAS_INT` starting index for `X`.
+
+```c
+CBLAS_INT c_isamax_ndarray( const CBLAS_INT N, const double *X, const CBLAS_INT strideX, const CBLAS_INT offsetX );

+### Examples
+
+```c
+#include "stdlib/blas/base/isamax.h"
+#include
+
+int main( void ) {
+ // Create strided array:
+ const float x[] = { 1.0f, -2.0f, 3.0f, -4.0f, 5.0f, -6.0f, 7.0f, -8.0f };
+
+ // Specify the number of element:
+ const int N = 8;
+
+ // Specify stride:
+ const int strideX = 1;
+
+ // Compute the index of the maximum absolute value:
+ int idx = c_isamax( N, x, strideX );
+
+ // Print the result:
+ printf( "index value: %d\n", idx );
+
+ // Compute the index of the maximum absolute value:
+ idx = c_isamax_ndarray( N, x, -strideX, N-1 );
+
+ // Print the result:
+ printf( "index value: %d\n", idx );
+}
