A 2x2 column major matrix.

Implementations

A 2x2 matrix with all elements set to 0.0.

A 2x2 identity matrix, where all diagonal elements are 1, and all off-diagonal elements are 0.

All NAN:s.

Creates a 2x2 matrix from two column vectors.

Creates a 2x2 matrix from a [S; 4] array stored in column major order. If your data is stored in row major you will need to transpose the returned matrix.

Creates a [S; 4] array storing data in column major order. If you require data in row major order transpose the matrix first.

Creates a 2x2 matrix from a [[S; 2]; 2] 2D array stored in column major order. If your data is in row major order you will need to transpose the returned matrix.

Creates a [[S; 2]; 2] 2D array storing data in column major order. If you require data in row major order transpose the matrix first.

Creates a 2x2 matrix with its diagonal set to diagonal and all other entries set to 0.

Creates a 2x2 matrix containing the combining non-uniform scale and rotation of angle (in radians).

Creates a 2x2 matrix containing a rotation of angle (in radians).

Creates a 2x2 matrix from a 3x3 matrix, discarding the 2nd row and column.

Creates a 2x2 matrix from the first 4 values in slice.

Panics

Panics if slice is less than 4 elements long.

Writes the columns of self to the first 4 elements in slice.

Panics

Panics if slice is less than 4 elements long.

Returns the matrix column for the given index.

Panics

Panics if index is greater than 1.

Returns a mutable reference to the matrix column for the given index.

Panics

Panics if index is greater than 1.

Returns the matrix row for the given index.

Panics

Panics if index is greater than 1.

Returns true if, and only if, all elements are finite. If any element is either NaN, positive or negative infinity, this will return false.

Returns true if any elements are NaN.

Returns the transpose of self.

Returns the determinant of self.

Returns the inverse of self.

If the matrix is not invertible the returned matrix will be invalid.

Panics

Will panic if the determinant of self is zero when glam_assert is enabled.

Transforms a 2D vector.

Multiplies two 2x2 matrices.

Adds two 2x2 matrices.

Subtracts two 2x2 matrices.

Multiplies a 2x2 matrix by a scalar.

Returns true if the absolute difference of all elements between self and other is less than or equal to max_abs_diff.

This can be used to compare if two matrices contain similar elements. It works best when comparing with a known value. The max_abs_diff that should be used used depends on the values being compared against.
