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)

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.

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.
