using predefined string for savefig

Im new to matlab so sorry about this.

I am trying to save a figure within a subroutine. The string to be used in the file name already exists. I know i could simply type it in but the filename depends on the parameters used in the particular data set; and there are 150 data sets.

the comands are as follows

fileparams = ['50psi_10A_Sawtooth_05Hz']

savefig(fileparams)

I get an error: "Undefined function or method 'savefig' for input arguments of type 'char'."

I have tried changing it to a cell string array and i get: "Undefined function or method 'savefig' for input arguments of type 'cell'."

How can i resolve this?

fileparams = ['50psi_10A_Sawtooth_05Hz']
filename = [fileparams '.fig']
print(filename)

Thanks. Exactly what i was looking for!

Ok well almost; it saves it as a .fig but it is unable to open it and i get an error dialog stating that it is not a binary MAT -file

[Marta Salas]

how do you open it? http://www.mathworks.es/es/help/matlab/ref/open.html

[Jairo]

it happens from windows explorer and from matlab when i doubleclick it on the upper left

[Jairo]

open('50psi_10A_Sawtooth_05Hz_P3P4.fig')

??? Error using ==> open at 163 Unable to read MAT-file Q:\~~~\50psi_10A_Sawtooth_05Hz_P3P4.fig: not a binary MAT-file. Try LOAD -ASCII to read as text.

Try this one instead of print

saveas(gcf,filename)

[Jairo]

There it is! thanks again.

What you have should work. The only thing that could get in the way is if you have a user-defined function that is also called savefig() within the search path of Matlab. Try

edit savefig

if it asks if you want to create it then you do not have another copy somewhere. If you are able to open it and "edit" it (i wouldn't edit it) then it might not be the same MATLAB savefig.

[Jairo]

It asks me to create it

[Jairo]

when i type in savefig it doesnt even recognize the function. Could it be because i am using an educatiuonal version?

[Jairo]

I am currently talking to Matlab tech to see what the problem is.

you should also look to see if the "set paths" are correct. (Files menu->Set paths) see if there are many many entries form C:\programfiles\Matlab\version\tool boxes etc.
