I'm wondering if there is a way the create multiple new arrays within a for loop.

I have the following equation that I'm trying to use.

The right hand side 3x1s are constant, but there are multiple values of z which then change 3x1 value on the left hand side.

Is there way that I could have z1 give LHS array 1, z2 give LHS array 2 and so within a for loop?

You wouldn't do that with a loop. You would just use vector arithemtic,

eps0=rand(3,1); %fake RHS data
kappa=rand(3,1);
z=rand(1,20);
eps=eps0+kappa*z;
epsxx=eps(1,:);
epsyy=eps(2,:);
gammaxy=eps(3,:);

Let's rename things a bit,

strain=eps0+kappa*z; %formerly eps=eps0+kapp*z

Here, strain will be a 3xN matrix whose columns are each of the N strains. So you have all of your results in that one matrix.

That makes a lot more sense. Thanks for your help!
