FFT function is not functioning.

Hello,

I'm trying to run a basic fft function:

...

x=linspace(0,5*pi,100);

y=sin(x);

Y=fft(y);

plot(Y)

...

When I do so, I get a download notifacation that fails. It reads as follows:

...

Loading

C:\Users\myname\OneDrive\Documents\bin\win64\builtins\mathdsp\mwlibmwmathdsp_builtinimpl.dllfailed

with error: The cloud operation was unsuccessful.

: unknown error: unknown error

...

How can I fix this?

Additional information:

• I have the signal processing toolbox installed.
• Running windows 10
• Prompting 'which fft' returns 'built-in (C:\Users\myname\OneDrive\Documents\toolbox\matlab\datafun\fft)'

It seems that you may have tried to install MATLAB on a cloud drive (OneDrive). Or maybe you copied the application files into OneDrive? I suggest that you reinstall MATLAB using the normal location for applications on your computer.
