mat2	translate (float x)
	Multiply by a translation matrix.
bit	isIdentity ()
	Return whether this is an identity matrix.
void	set (int col, int row, float value)
	Set a cell on the matrix.

mat2	transpose ()
	Get the transpose matrix.
mat2	mul (mat2 mb)
	Multiply matrices.
float	mul (float v)
	Multiply matrix by one-extended scalar.
vec2	mul (vec2 v)
	Multiply matrix by vector.
bit	eq (mat2 b)
	Test for equality.
void	print ()
	Print the matrix.
char[]	toString ()
	Convert to a four-line string.
Static Public Member Functions
mat2	create (vec2 a, vec2 b)
	Create a matrix using normal order.
mat2	create (float aa, float ab, float ba, float bb)
	Create a matrix using normal order.
mat2	identity ()
	Get the identity matrix.
mat2	scaling (float x)
