Create large complex matfile

Hello,
how can you create a large complex array in a matfile without allocating memory for the whole array?
The following works perfectly well for real data:
matObj = matfile(filename, 'Writable', true);
matObj.data(rows,cols,channels,channels) = 0;
I tried changing it to:
matObj = matfile(filename, 'Writable', true);
matObj.data(rows,cols,channels,channels) = 1i;
which raises the following error:
The class and attributes of the right hand side could
not be converted into the type of the variable in the
file.
Thank you in advance!

Just make sure that the first thing written is complex.
If the array is not already complex in the file, you will probably need to rewrite it all.
Note: if you need a complex value that happens to be (0,0) then use
complex(0,0)
