Hi,
Through my matlab program, I'm generating several matrices. I would like to save the matrices into a .m file. Is this possible?
The reason I say .m file because I would liek o see the matrices in the same format as that when they appear in the command window after typing
disp(my_matrix)
How to store the matrices in .m (or any other preferred) file?
2) Secondly, I'm generating several two dimensional plots through my matlab program. How do I save these plots?

A=[1 2;3 4]
save filename A % use load filename to get the matrix A
To save a figure, use saveas or hgsave

Thanks a lot, I used the following
h=figure;
plot(x,y);
saveas(h,filename,'fig');
I get the files with .fig extention.
But if I open these files with Matlab, file->Open, there is no action i.e. the files do not open up.
If I change the extension to "bmp", the bmp file open up and is correct.
I would like to save it as a matlab figure and be able to open it in matlab.
Why does the .fig file doesn't open up?

I don't know why this is happening to you. There is another way to save your plots
h=plot(1:10) % Example
hgsave(h,'filename')
To get your plot
hgload('filename')

The format you need to use to enter matrices in .m files is not compatible with the format that is output by disp()
You should look at the -ASCII flag of save(), and you should look at mat2str()
