L_LTKRN_API L_BOOL L_Matrix_IsIdentity(matrix)

Indicates whether the specified L_MATRIX is an identity matrix.


const L_MATRIX* matrix

Pointer to the L_MATRIX to test.


Value Meaning
TRUE The L_MATRIX is an identity matrix.
FALSE The L_MATRIX is not an identity matrix.


An identity matrix has a value of 1 in coefficients [1,1],[2,2],[3,3] and a value of 0 in the rest of the coefficients. This correlates to setting m11 and m22 to 1 and m12, m21, offsetX, and offsetY to 0.

In an affine matrix, coefficients [3,1],[3,2],[3.3] are implied to always have the values 0,0,1 respectively.
