How can I use the imgaussfilt() function to process several images i have already saved into an array in the workspace?

Here is the code I have so far...

clear
imagelist = dir('*.png');
N = numel(imagelist);
imdata = cell(1, numel(imagelist));
for k = 1: N
    imdata{k} = imread(imagelist(k).name);
end

for i = 1:N
    noiseless{i} = imgaussfilt(imdata(i))
end

This code succesfully saves the seven png images in an array and its possible, using imshow(imdata{7}) to display any image saved. Now i am trying to create a new array using the gaussfilt() function to reduce the noise level in each of the seven images. The error that I'm getting is

>> noiseforstack
Undefined function 'imgaussfilt' for input arguments of type 'cell'.

Error in noiseforstack (line 11)
    noiseless{i} = imgaussfilt(imdata(i))

Obviously I am not using the function correctly however I am not sure how to fix the problem. Any help would be greatly appreciated.

Thank you!

It looks like you are sending a cell array to the imgaussfilt function instead of just a single image. Watch your indexing. Change

noiseless{i} = imgaussfilt(imdata(i))

to

noiseless{i} = imgaussfilt(imdata{i})
