find the size of matrix m such that size(reshape(m,1,1,25))=(25,1,1) in matlab

To find the size of matrix m such that size(reshape(m,1,1,25)) = (25,1,1), you can use the size function in MATLAB after reshaping the matrix. This can be achieved as follows:

main.m
% Define the matrix m
m = randn(5, 5);

% Reshape the matrix into a 1x1x25 matrix
m_reshaped = reshape(m, 1, 1, 25);

% Check the size of m_reshaped
size_m_reshaped = size(m_reshaped)

% Output:
% size_m_reshaped =
% 
%    25    1    1

The size function returns a row vector containing the number of elements in each dimension of the input matrix. Here, size_m_reshaped contains [25 1 1], indicating that m_reshaped has 25 elements along the first dimension and 1 element each along the second and third dimensions.
