.mat file to csv.

I have a mat file named (bag.mat) with value 1*1 bagOfFeature on my workspace. I want to write it into csv files. I have tried csvwrite function but i got the error:

c = load('bag.mat'); %On my workspace, c has a value of 1*1 struct csvwrite('file.csv', c);

Error using csvwrite (line 47)

Undefined function 'real' for input arguments of type 'struct'.

Attaching my mat file.

I will appreciate your assistance.

Thanks you

csvwrite only takes matrices as input, bagOfFeatures is a struct. You should specify what you want your output to look like. You could for example extract some parameters from the struct like this:

csvwrite('mybagdata.csv', [bag.VocabularySize; bag.GridStep'; BlockWidth']);

Or you could use fprintf to write headers too.
