error in mat to csv conversion

load('fif.mat'); csvwrite('fif.csv', fif); ERROR: convert Error using dlmwrite (line 130) Could not open file fif.csv

Error in csvwrite (line 43) dlmwrite(filename, m, ',', r, c);

Error in convert (line 2) csvwrite('fif.csv', fif);

the code is loading file but not converting it.

After running load('fif.mat'); is there a variable in your workspace called fif? If so, what are the contents and data type?

You are passing fif to csvwrite as if it's a workspace variable. If you have a double array called fif in your workspace, that would work.

yes it loads a mat file named as 'fif' that contains 21*96 complex double data e.g 2.023672462915360 + 0.000000000000000i. I jst want to convert this mat file to csv. yes Im also storing in my code these values in a variable called fif. it worked previously bt now suddenly showing this error.

• You might be cd'd to a directory that you cannot write to
• fif.csv might already exist but have its security set so that you cannot write it

Look at

cd
fileattrib('.')
which fif.csv
fileattrib('./fif.csv')

C:\Program Files\MATLAB\R2013a\bin

No such file or directory.

You are in a directory you cannot write into. You need to

cd E:\SEMESTERS_WORK\MS_2k14\THESIS\code by date\csv
