Regarding plot display issue
显示 更早的评论
I am unable to view the plot after giving plot command. The figure window looks blank. I am attaching a snap of how it looks. Please help me with this.

You're either 1) not specifying the axis handle and it's being plotted on another figure, 2) the axes are positioned outside of the visibile figure, 3) an error is stopping the execution of the plot.

Add

close all
figure
in front of above sequence of commands and report back.

So, another figure/axis was active instead of the one you though/intended...

Get in the habit of specifying the parent of graphics objects.
Examples:
fig = figure();
ax = axes(fig);
plot(ax, rand(1,10))

What can happen to cause the symptom you saw before is, that without code between the time you created the figure you intended to plot into you may have looked at another figure manually. That user intervention would have changed the current axes from the figure so that the implicit handle in a plot() command without an explicit reference would use gca -- the one then being pointed at, not the figure that was created.
That's just one easy to visualize way that focus can change sorta' unexpectedly -- there are many other ways besides...hence the recommendation to always be safe when coding.
