3 Basic Program Components Evaluating in Another Workspace Using evalin. Functions can also obtain variables from either the base or the caller’s workspace using the evalin function. The example below, compareAB_1, evaluates a command in the context of the <strong>MATLAB</strong> command line, taking the values of variables A and B fromthebaseworkspace. Define A and B in the base workspace: A = [13 25 82 68 9 15 77]; B = [63 21 71 42 30 15 22]; Use evalin to evaluate the command A(find(A
Variables global B C = A(find(A
