Implementations

impl<'a, T: Scalar, R: Dim, C: Dim, RStride: Dim, CStride: Dim> MatrixSlice<'a, T, R, C, RStride, CStride>

Creating matrix slices from &[T]

pub unsafe fn from_slice_with_strides_generic_unchecked(
    data: &'a [T],
    start: usize,
    nrows: R,
    ncols: C,
    rstride: RStride,
    cstride: CStride
) -> Self

Creates, without bound-checking, a matrix slice from an array and with dimensions and strides specified by generic types instances.

Safety

This method is unsafe because the input data array is not checked to contain enough elements. The generic types R, C, RStride, CStride can either be type-level integers or integers wrapped with Dynamic::new().

pub fn from_slice_with_strides_generic(
    data: &'a [T],
    nrows: R,
    ncols: C,
    rstride: RStride,
    cstride: CStride
) -> Self

Creates a matrix slice from an array and with dimensions and strides specified by generic types instances.

Panics if the input data array dose not contain enough elements. The generic types R, C, RStride, CStride can either be type-level integers or integers wrapped with Dynamic::new().
