I want to know how to create a struct type mat file

how to create a struct type mat file with different fields .for example in this way .can anyone please help me create a mat file in this way ,thank you in advance.

[Bob Thompson]

I'm not sure I understand what you mean by a 'struct type mat file'. A mat file stores matlab workspace entities, which can include structure variables. Is that an acceptable solution?

[Walter Roberson]

result = cell2struct({currency.feature}, {currency.name}, 2);

The result would be a struct with fields named 'Dollar', 'pound', 'rupee', 'yen', with value according to the feature value.

I am having 24 images in currency folder .I am getting error while I am using cell2struct in my code .Can yoy please suggest we how to use in my code.Thank you in advance

MyFolder = 'M:\matlab programs\currency';

FilePattern = fullfile(MyFolder, '*.jpg');

TheFiles = dir(FilePattern);

for k = 1 : length(TheFiles)

BasefileName = TheFiles(k).name;

FullFileName = fullfile(MyFolder, BasefileName);

im=imread(FullFileName);

%preprocessing

%resize image

im=imresize(im,[128 128]);

%remove noise;

%seperate channels

r_channel=im(:,:,1);

b_channel=im(:,:,2);

g_channel=im(:,:,3);

%denoise each channel

r_channel=medfilt2(r_channel);

g_channel=medfilt2(g_channel);

b_channel=medfilt2(b_channel);

%resltore channels

rgbim(:,:,1)=r_channel;

rgbim(:,:,2)=g_channel;

rgbim(:,:,3)=b_channel;

%featureextraction

[fet1,fet2,fet3]=totalfeature(rgbim);% calls the function totalfeature

fet(:,k)=[fet1;fet2;fet3]; % fet has the 78 features of each image

end

save('fet.mat');

%Total feature code:

function [fet1,fet2,fet3]=totalfeature(rgbim)

%color feature

fet1=color_luv(rgbim);

%edge feature

fet2=edgehist(rgbim);

%texture feature

%glcm-gray level co occurrence matrix

glcm=graycomatrix(rgb2gray(rgbim));

fet3=glcm(:);
