Hello, i am trying to change all the elements in a single line matrix from Xj to 1/Xj. Thanks

Answer 1

X=1./X;

Use a dot for element-wise division and multiplication.

Hey, thanks for taking the time to answer. I see now i did not word the question correctly; I meant in a single line of a matrix,not a matrix with just one line :)

[Walter Roberson]

X(5,:) = 1./X(5,:);

Answer 2

A=rand(n);

A(:,n)=1./A(:,n);

This would change a single column, rather than a single line (row). It happens to change the last column, by the way.
