Error in untitled (line 3)

[B, src] = eprload ('data.DTA');

plot(B, src + 0.1);

i = quad2d([B, src + 0.1], 3480, 3560 , -10, 10);

I need to integrate the function from the file twice. I don't quite get, why the code won't work...

The first argument to quad2d needs to be a function handle.

I am not familiar with eprload, but its output looks like (x,y) data. I think you might need to use the trapz function instead of quad2d, to do a numerical integration.
