end
My database contains 100 greyscale images. I need to convert them into matrices with each cell containing a matrice of uint8 form of each image.

Refer to Access Data in Cell Array.
In the above code, index the Cell Array with with Curly Braces, {} & not Smooth Parentheses, () in the for loop ie., change the code in the for loop to:
for i=1:m
A_result{1,i}=imread(strcat('E:\Notes\SEM 7\PRML\Alphabet Database\A\',A_folder(i).name));
B_result{1,i}=imread(strcat('E:\Notes\SEM 7\PRML\Alphabet Database\B\',B_folder(i).name));
C_result{1,i}=imread(strcat('E:\Notes\SEM 7\PRML\Alphabet Database\C\',C_folder(i).name));
D_result{1,i}=imread(strcat('E:\Notes\SEM 7\PRML\Alphabet Database\D\',D_folder(i).name));
E_result{1,i}=imread(strcat('E:\Notes\SEM 7\PRML\Alphabet Database\E\',E_folder(i).name));
end
