How to plot this signal?

dt= 0.0001;
t = 0:dt:10;
ht= abs( (1/2*pi*j*t)*( exp(j*1460*pi*t) - exp(j*1450*pi*t)) );
plot(t,ht)
title(' plotting h(t)')
xlabel(' Time')
ylabel(' h(t)')
grid on

I want to plot this signal in Octave or Matlab, but it dosen't work, and I don't know why it dosen't plot.

ht= abs( (1/2*pi*j*t).*( exp(j*1460*pi*t) - exp(j*1450*pi*t)) );
% Add this ----------^

".*" is element-wise multiplication.

"*" is matrix multiplication and requires size-agreement between the two values you are multiplying.

thank you. Got the graph

Looks like you're using the imaginary unit j. I initially thought j may have been a variable not included in your question. That doesn't impact the answer, just double checking that this is your intention.

Yes, this was my intention
