So I'm basically writing a matlab code that will automatically solve a simple circuit (just resistors, current sources and voltage sources) using nodal analysis. All I want the user to do is input values for R, the resistance, or I the current sources. (voltage sources will be transformed into current sources with source transformation.) If I initialize R as a 4x4 matrix consisting of 'inf' in each slot, how would I allow the user to input their own resistances? Using R(2,3)=5 or whatever.

You could consider using a uitable to allow the user to modify the values, and have a uicontrol to trigger the action.
