L2 norm of the column

How can I write the code to find the L2 norm of the column (G`)ij as shown in the picture below. In my code I have used M instead of G.

M_norm = normc(M)

Thank you for your response. The formula given in the picture is in sqrt form can you please elaborate that?

[Torsten]

Yes, it's the usual L2 norm of the j'th column of G. What is there to elaborate ?

[Heya :)]

Its giving me error in the MATLAB program.

[Torsten]

Please include code and error message.

[Heya :)]

ok

If G is the matrix you want to normalize, then G' = normc(G).

I think that G=M in your code, but I'm not sure.
