How to get the figures from IRI model?

Dear All,

I would like to use IRItest code that is written by Drew in this Matlab website, however I received an error that I do not know how to resolve it.

Would you please help me to run his code?

Here is the error that I have received.

Here is the link for code: https://www.mathworks.com/matlabcentral/fileexchange/34863-international-reference-ionosphere-iri-model

Thank you with my best regards,

Ara

Do you have the Parallel Computing Toolbox installed and licenced ?

Thank you for your help. I have just checked it and it is installed and licenced in my Matlab.

What is the full error you are seeing? Without more information, the most likely suspect in that line is the parfor. It's possible that there is an issue with your setup/configuration. You can try reinstalling the toolbox. First, I would try running the code again, but change useparfor to false and see if you still have an error.

Thank you Eric for your reply. Here is the full error:

Curl command did not work. It returned status:1,
'"C:\Users\I7-2600K\Documents\MATLAB\curl"' is not recognized as an internal or external command,
operable program or batch file.

I noticed that issue you are facing related to the "curl" command when using the provided files. This error occurs because the "curl" command is not included by default in Windows operating systems.

The author has provided an instruction for installation of “curl” command in the "iri2016.m" file, which is part of the files you have downloaded from the exchange link you shared.

If you have any further queries regarding any files you have downloaded from the MATLAB Files Exchange, you can reach out to the Discussions section of that specific file exchange post.

Hi Madheswaran,

Thank you for your response. I did check the "Curl" and it is install in my system but I do not know why it does not run the code. In 2013, I was able to run and plot the data but with the new version of code, I am unable to run it.
