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)'

请先登录，再回答此问题。

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.
