yes. It didn't work for me either.
Below is the list of steps followed:
1. Log in to the sage webserver with firefox browser.
2. create a new worksheet.
3. select the matlab option in the list of softwares available.
4. write the below code in the editor
Delay = [1 2 3 4 5 6]
Vctrl = [0.781 1.025 1.19 1.37 1.469 1.533]
plot(Vctrl,Delay)
savefig('nicefig2', 'png', '-rgb', '-c0.1', '-r250')
5. press evaluate.
The simple matlab code I wrote is functional and the sage server
evaluates it properly and generates the .png file in the directory.
Only issue that need to be addressed is to get the sage server display
the plots in the web browser itself. We are planning to provide this
to a set of students who take summer classes and
it would be really great if we can get this working.
rightnow, this creates the nicefig2.png file in the directory home/
sageserver/matlab/user/
Is it something to do with the directory it writes?
Thank you all for your sincere replies.
