+
+#### stdlib_strided_dnanstdevyc( N, correction, \*X, strideX )
+
+Computes the [standard deviation][standard-deviation] of a double-precision floating-point strided array ignoring `NaN` values and using a one-pass algorithm proposed by Youngs and Cramer.
+
+```c
+const double x[] = { 1.0, -2.0, 0.0/0.0, 2.0 };
+
+double v = stdlib_strided_dnanstdevyc( 4, 1.0, x, 1 );
+// returns ~4.3333
+```
+
+The function accepts the following arguments:
+
+- **N**: `[in] CBLAS_INT` number of indexed elements.
+- **correction**: `[in] double` degrees of freedom adjustment. Setting this parameter to a value other than `0` has the effect of adjusting the divisor during the calculation of the [standard deviation][standard-deviation] according to `N-c` where `c` corresponds to the provided degrees of freedom adjustment. When computing the [standard deviation][standard-deviation] of a population, setting this parameter to `0` is the standard choice (i.e., the provided array contains data constituting an entire population). When computing the corrected sample [standard deviation][standard-deviation], setting this parameter to `1` is the standard choice (i.e., the provided array contains data sampled from a larger population; this is commonly referred to as Bessel's correction).
+- **X**: `[in] double*` input array.
+- **strideX**: `[in] CBLAS_INT` stride length for `X`.
+
+```c
+double stdlib_strided_dnanstdevyc( const CBLAS_INT N, const double correction, const double *X, const CBLAS_INT strideX );

+
+ // Specify the number of elements:
+ const int N = 6;
+
+ // Specify the stride length:
+ const int strideX = 2;
