how to plot graph using fplot command
显示 更早的评论
syms x
y=exp(x)
fplot(y)
I got the following errpor. If I replace exp(x) by sin(x) then the code shows graph in the default range

What error?
The code seems to be working fine here and on my R2021a.
syms x
y = exp(x);
fplot(y)
Also, run this code and share the output you get.
which exp -all

How is it not working?
If you get an error, share the full error mesage i.e all of the red text.
if something else, then specify in detail.

Alt syntax for using fplot is this one:
FUN = @(x)exp(x);
fplot(FUN), grid on
figure
% Or a bit better controlled way by specifying the range of x values
fplot(FUN, [-2, 2])
grid on

It is likely that you have saved one of your MATLAB files by fplot.m name or you have named/stored one of your variables by fplot.
(1) Run this command:
>> which fplot % See whether it is a MATLAB builtin function or variable or you saved M-file
If it is one of your saved M-files, just rename your M-file, e.g.: fplot_1.m
(2) Run this command:
>> clear all
(3) Now, you should be able to execute fplot() fcn.
All the best.
