Help With plotting 3D Graph

Say I have a function psi, given as a series of x values and time.

psi=@(t)(abs(x_1.*exp(((-(t.^2))./(x_3.^2))+((i*x_4.*(t.^2))/(2))+(i*x_6))));

x_3, x_4 and x_6 and t are matrices of length 2000.

I need to calculate psi for every value of t.

So Like:

psi(1) = abs(x_1.*exp(((-1)./(x_3.^2))+((i*x_4)/(2))+(i*x_6))));

I get 2000 values. But i need to do this for 2000 values of t.

So psi needs to be a 2000x2000 matrix.

Annoyingly, ive got the concepts down, but the syntax is stumping me.

Use:

t=t.';

then call

Result = psi(t)

Also make sure that t is length needed --> here 2000

Hi steven, inverting the t matrix worked a charm. I was overcomplicating it with multiple for loops, which causwd my laptop to crash.

You wnat a good laugh? I saw this answer two houors ago, and then spent the following two hours trying to plot using plot3, only to figurre out i neeeded mesh about ten minutes ago.

Im tired, im off for a nap. thanks man.
