You put a line of code before the first function. You can only do that if you intend your file to work as a script, and if you close all functions with the end keyword. You seem to be doing neither.

You should remove the cd line from your file.

i removed but then it shows this error Curl command did not work. It returned status:1,

'"E:\MATLAB\Data\curl"' is not recognized as an internal or external command,

operable program or batch file.

[Arun Kumar Singh]

http://curl.haxx.se/download.html. here is the website to download CURL. if you could fix the code and make it in working mode.

[Rik]

If I install curl on my computer that will not fix the issue on your computer. Judging from that error message I would suggest you install curl in E:\MATLAB\Data\.

[Arun Kumar Singh]

i already did it and important thing is when i remove cd line from file it shows this error Curl command did not work. It returned status:1,

'"E:\MATLAB\Data\curl"' is not recognized as an internal or external command,

operable program or batch file.

but when i enter that line in code it shows

Does the file E:\MATLAB\Data\curl.exe exist?

[Arun Kumar Singh]

yes it does

[Arun Kumar Singh]

https://curl.haxx.se/download.html you can also try downloading from here, kindly do it i need it for my research purpose.

Thanks in advance

[Arun Kumar Singh]

Thank you it worked

[Rik]

What does this line return?

system('"E:\MATLAB\Data\curl" -h')

• If it returns an error, then your system can't actually find curl. That is something you need to fix.
• If it doesn't return an error there is something wrong with the function. Contact the author of the function.
