Brace indexing into the result of a function call is not supported

Hello I was attempting to run a code I had. The code is below:
%focus stacking function using Laplacian pyramid
function resultImage = focusStack(imageStack)
numImages = numel(imageStack);
%Convert images ti double for processing
for i = 1:numImages
imageStack{i} = im2double(imageStack{i});
end
%Initialize Laplacian pyrimid for each image
laplacianPyramid = cell(1 , numImages);
for i = 1:numImages
laplacianPyramid{i} = laplacianPyramid(imageStack{i});
end
%combine Laplacian pyramid to create the final result
blendedPyramid = blendLaplacianPyramids(laplacianPyramid);
%Reconstruct the final focus-stacked Image
resultImage = reconstructFromPyramid(blendPyramid);
end
% Laplacian pyramid generation for an image
function pyramid = laplacianPyramid(image)
levels = 6; %Number of pyramid levels (adjust as needed)
pyramid = cell(1, levels);
pyramid{1} = image;
for i = 2:levels
smoothed = imgaussfilt(pyramid{i-1}, 2); %Apply Gausian smoothing
difference = pyramid{i-1} -smoothed; %Compute difference
pyramid{i} = difference;
end
end
%blend the laplacian pyramid to create the final result
function blendedPyramid = blendLaplacianPyramids(pyramids)
numLevels = numel(pyramid{1});
blendedPyramid = cell(1, numLevels);
for level = 1:numLevels
blendedLevel = zeros(size(pyramids{1}{level}));
for level = 1:numel(pyramids)
blendedLevel = blendedLevel + pyramid{1}{level};
end
blendedPyramid{level} = blendedLevel;
end
end
%Reconstruct image from blended Laplacian
function resultImage = recontructFromPyramid(pyramid)
numLevels = numel(pyramid);
resultImage = pyramid{numLevels};
for level = numLevel-1:-1:1
expanded = imresize(resultImage, size(pyramid{level}), 'bilinear');
resultImage = expanded + pyramid{level};
end
end
I ran the code above and got the following error:
Error: File: focusStack.m Line:
40 Column: 23
Brace indexing into the result
of a function call is not
supported. Assign the result of
'pyramid' to a variable first,
then brace index into it.
Do you know of a way to resolve this issue.

Hm. I'm going to guess on this one.
function blendedPyramid = blendLaplacianPyramids(pyramids) % the variable is 'pyramids'
numLevels = numel(pyramid{1}); % but it's singular here
blendedPyramid = cell(1, numLevels);
for level = 1:numLevels
blendedLevel = zeros(size(pyramids{1}{level})); % plural here
for level = 1:numel(pyramids) % plural here
blendedLevel = blendedLevel + pyramid{1}{level}; % singular here
My guess is that 'pyramid' is supposed to be 'pyramids'. Since 'pyramid' isn't a defined variable, it's instead resolving as a function somewhere on your path and causing the admittedly confusing error.
