I'm reading a bunch of these strings from a .txt file, and I want to use these strings to make complex numbers.

i.e. I have a string mc = '(1., 0.)' and I want to use that as the parameters for the complex function so I get complex(1.,0.) or complex((1., 0.)).

UPDATE: I figured out that I can use the sscanf function, but I'm still wondering if there is a more efficient way of doing this.

The easiest way is probably to use sscanf:

mc = '(1.2, 0.)';
mn = sscanf(mc, '(%f,%f)')';
mz = complex(mn(:,1), mn(:,2))

Experiment to get the result you want.
