When I plot just one row from matrix it plots fine, but when I plot it with some other signals it always turns to zero. It only works when I plot ti alone, why?

Even when I plot both rows from matrix, that second one becomes zero and first one is displayed fine.

plot(t,I(2,:) this works and its not zero plot(t,I) this just display the first row and turns second to zero

What is there in second coln of I? All zeros I guess.

They probably have significantly different scales.

Try this:

figure(1)
subplot(2,1,1)
plot(t, I(1,:))
grid
subplot(2,1,2)
plot(t, I(2,:))
grid

Thank you, it works! Is there any way it could work on one graph?

My pleasure!

To get it to work with one ‘t’ axis, I would use the yyaxis (in R2016a and later) or plotyy (earlier versions) function.
