How to calculate approximation error from 1x1 and 1x1001 symbolic signals

Hi,

I need to calculate the approximation error from two signals, one is a triangularPulse function from matlab( which generates 1x1 symbolic), and the other one is a 1x1001 symbolic. How can I split the triangularPulse into a 1x1001 array so I can calculate the error?

Much depends opn how you defined your triangularPulse.

One option:

syms x T(x) 
T(x) = triangularPulse(x);

Tfcn = matlabFunction(T);
t = linspace(-1, 1, 1001);
Tvct = Tfcn(t);

figure
plot(t, Tvct)
grid on

The plot call simply presents the result. It is not necessary for the code.

Experiment to get the result you want.
