Linewidth for function step?
显示 更早的评论
I plotted something but not sure why I can't adjust the linewidth of the result of the plot. I was able to change colors but linewidth doesn't change.
step(value_1);
set(value_1, 'LineWidth', 2);

Get the outputs of the step function, then plot them using a plot call:
[y,t] = step(value_1);
figure
plot(t, squeeze(y), 'LineWidth',2)
grid
The Control System Toolbox plot functions do not allow you to alter their properties easily, if at all.

There have been recent enhancements to customize these linear analysis plots at command line more easily. Using stepplot, this customization can be done at the time of creation of the plots or after. For example, to change the line width at the time of creation (R2026a and later), you can now do,
stepplot(sys, 'LineWidth', 2)
To customize the response after creation (R2024b and later),
sp = stepplot(sys);
sp.Responses.LineWidth = 2;

This technique works for step, impulse, nyquist, and bode plots
LineWidth = 3;
s = tf(s)
sys = 1/(s+1)
figure; step/impulse/nyquist/bode(sys)
set(findall(gcf,'type','line'),'linewidth',LineWidth);
