WebbNotice that if the determinant of matrix 𝐴 is equal to zero, the inverse cannot exist. If the determinant is not zero, matrix 𝐴 will have an inverse. We then call matrix 𝐴 invertible or nonsingular. The properties of inverse matrices we will consider in this lesson will apply to all invertible matrices. WebbAn identity matrix would seem like it would have to be square. That is the only way to always have 1's on a diagonal- which is absolutely essential. However, a zero matrix could me mxn. Say you have O which is a 3x2 matrix, and multiply it times A, a 2x3 matrix. That is defined, and would give you a 3x3 O matrix. WebbThe matrix is invertible if and only if its determinant is different to zero. In later lessons we will talk about the invertible matrix theorem which gives a series of conditions equivalent to the statement above, that if met, define an invertible matrix. super top zurnalas
