## Main Question or Discussion Point

In the Matlab program below

U=[210; 100; 150]

ky= linspace(-.2,.2);

qx=sqrt(((150-U)/.2)^2-ky.^2)

I want to have qx as a matrix in which each row is corresponding to one value of U: the first row corresponds to 210, the second to 100 and .... How should I do this? (I want to avoid the "for loop" if possible).
