I have this matrix here:
Wc=[0 0.285714285714286 0 0.918367346938775 0 9.83965014577259
0.285714285714286 0 0.918367346938775 0 9.83965014577259 0
0 -0.214285714285714 0 -2.29591836734694 0 -24.5991253644315
-0.214285714285714 0 -2.29591836734694 0 -24.5991253644315 0
0 -0.214285714285714 0 -2.29591836734694 0 -24.5991253644315
-0.214285714285714 0 -2.29591836734694 0 -24.5991253644315 0];
The rank of this matrix is 4 because column 3 and column 4 are linearly dependent. How can I use MATLAB to replace column 3 and column 4 with columns that will make the rank full (six)?

Trivial.
Replace the offending columns with vectors of random numbers. DONE. With probability 1, the result will be full rank. NOT random integers. Use rand, or randn.
