Function from_column_major_slice

pub fn from_column_major_slice<E>(
    slice: <<E as Entity>::Group as ForType>::FaerOf<&[<E as Entity>::Unit]>,
    nrows: usize,
    ncols: usize,
) -> MatRef<'_, E>
where
    E: Entity,

Creates a MatRef from slice views over the matrix data, and the matrix dimensions. The data is interpreted in a column-major format, so that the first chunk of nrows values from the slices goes in the first column of the matrix, the second chunk of nrows values goes in the second column, and so on.

Panics

The function panics if any of the following conditions are violated:

• nrows * ncols == slice.len()

Example

use faer::mat;

let slice = [1.0, 2.0, 3.0, 4.0, 5.0, 6.0_f64];
let view = mat::from_column_major_slice::<f64>(&slice, 3, 2);

let expected = mat![[1.0, 4.0], [2.0, 5.0], [3.0, 6.0]];
assert_eq!(expected, view);
