How do I apply a transformation in a image

I'm using tform = maketform('affine',A); and it throws this error:

A =

     1.0e+15 *

     0.000000000000001                   0                   0
                     0   0.000000000000001                   0
    -0.000482575874560   0.005428978588800  -2.256162857536641

Error using maketform>validate_matrix (line 317)
The final column of A must consist of zeroes, except for a one in the last
row.

but the final column is zeros, except the one in the last row. what am i doing wrong?

but the final column is zeros, except the one in the last row

The error message doesn't say "the one" in the last row. The error message says "a one" in the last row.

The final column should be [0;0;1], assuming the transformation you're doing is in 2D.
