problem to install IQC toolbox

Hi everyone

I tried to install IQCtoolbox with several methods provided by available sources, but none worked well.

I got errors that are not clear.

I followed all the provided steps by

https://iqctoolbox.github.io/iqcToolbox/getting_started.html

I tried using web save, add-on, direct download,

while I type:

installIqcToolbox

it asked me to install YALMIP, I pressed y then asked to install LPSOLVE 5.5 I pressed y, then asked to install SDPT3 I pressed y but returned the error:

>> installIqcToolbox

Hi Sharara,

I understand that you are facing issues while installing the IQC toolbox. I had installed the same without any errors. The warning about an existing directory suggests that some parts of the toolbox (SDPT3 in this case) might already be installed. Ensure that previous installations are completely removed before attempting a fresh installation.

Before running the installation script again, clear MATLAB’s path cache by running the following command in the MATLAB command window:

rehash toolboxcache

If the issue persists, you can consider debugging the installation script by setting up breakpoints in the code or update to the latest version of MATLAB.

For more information about “rehash” and debugging, you can refer the following documentation:

Hope this helps!
