Formulation to Matlab code

How to write this formulation in Matlab:

where p = 1; g is a vector; j= length(g); x is a vector

phi = sum( norm(max(0,g)) );   

phi = max( max(0,g) );

are they corect or not?

Ensure your max usage is correct

max(A,B) returns an array with the largest elements taken from A or B.

If this is correct for your application then the sum, norm is correct, you need to raise your first equation to the pth power also.
