In matlab, although my matrix is full rank, the solution is still incorrect.Ax=b,A(10000*10000),x、b(10000*1)
This is equation solving
this is D matrics
this is J matrics
I want to test
but the result is not good
My ultimate goal is to use the constructed inverse matrix to restore the image, because the deviation in the solution causes the restoration effect not to be very good：
The above picture is restored by me directly using the inverse matrix. The picture below is restored by using the constructed inverse matrix. The inverse matrix is J and the constructed inverse matrix is Dx1.
