I have difficulties in making a function to extract columns after first number in the row from a the matrix. For example I have this matrix (A) and I want all columns that have first element 1 to be extracted in another matrix
A= 1 2 1 1 3
2 5 6 4 8
2 3 5 7 8
And I want my function to return this:
B= 1 1 1
2 6 4
2 5 7

Ciuban, use
B = A(:,A(1,:)==1)

Sure
function B = extr(A,extrnum)
B = A(:,A(1,:)==extrnum);
end
