Function rgsl::cblas::level1::sscal

pub fn sscal(N: i32, alpha: f32, x: &mut [f32], incx: i32)

Multiple each element of a matrix/vector by a constant.

Postcondition: Every incX'th element of X has been multiplied by a factor of alpha

Parameters:

• N : number of elements in x to scale
• alpha : factor to scale by
• X : pointer to the vector/matrix data
• incx : Amount to increment counter after each scaling, ie incX=2 mean to scale elements {1,3,...}

Note that the allocated length of X must be incX*N-1 as N indicates the number of scaling operations to perform.
