`void`	`set(int i, int j, float val)`	Sets the (i,j)th element of this matrix, where i is the row index and j is the column index
`Mat2f`	`toMat2f()`	If this is a 2x2 matrix, returns it as a Mat2f.
`Mat3f`	`toMat3f()`	If this is a 3x3 matrix, returns it as a Mat3f.
`Mat4f`	`toMat4f()`	If this is a 4x4 matrix, returns it as a Mat4f.
