MATLAB: How to save a workspace data to a specific directory.

save

I want to save the mean image matrix(Back_m) into a following folder 'C:\Users\YJ\Desktop\matlab' Here is what I did
clc;
clear;
back_path = 'F:\Thesis data\sample\datachris\Intensifier_Off\';
back_files = dir([back_path '*.im7']);
n_back=length(back_files);
n_im=length(back_files);
A1 = readimx([back_path back_files(1).name]);
% All_back_data = zeros(A1.Nx,A1.Ny*A1.Nf,n_im);
All_back_data = zeros(A1.Nx,A1.Ny*A1.Nf,n_im);
for i = 1:n_im
temp = readimx([back_path back_files(i).name]);
All_back_data(:,:,i) = double(temp.Data);
end
Back_m = mean(All_back_data);
figure;imshow(temp.Data(:,1:768),[]);colormap jet;colorbar
savdir = 'C:\Users\YJ\Desktop\matlab\';
save(fullfile(savdir,Back_m),'backmean');
And I get the following result:
Error using fullfile (line 59) Char inputs with multiple rows are not supported.

You got confused over the name of the file and the name of the variable, it should be:
save(fullfile(savedir, 'backmean'), 'Back_m'); %maybe also add extension to backmean
