Type Definition zoea::mtx::DMatrix

type DMatrix<N> = Matrix<N, Dynamic, Dynamic, <DefaultAllocator as Allocator<N, Dynamic, Dynamic>>::Buffer>;

DMatrix operations

The nalgebra crate contains greate functionality for DMatrix manipulations. The mtx module of Zoea makes it easy to create nalgebra matrices.

Quickstart:

Create a new 5x5 f64 identity matrix and print the first column

use zoea::mtx;
let mut m = mtx::new_f64_identity(5);
println!("Here is the first column: {}", m.column(0));

Create a 3x1000 f32 random matrix with values between -1 and 1 Create a 1000x4 f32 random matrix with values between 5 and 25

use zoea::mtx;
let a: mtx::DMatrix<f32> = mtx::new_f32_random(3, 1000, -1f32, 1f32);
let b: mtx::DMatrix<f32> = mtx::new_f32_random(1000, 4, 5f32, 25f32);
// multiply a and b and print the result
let c: mtx::DMatrix<f32> = a * b;
println!("{}", c);
 
// take one of the values and assign it to a float
let select_element: f32 = c[(1,3)];

A dynamically sized column-major matrix.
