could anyone help me to solve the issue

I am having a matrix

A=[0.0037 0.0036 0.0034 0.0033 0.0032 ;

0.0064 0.0066 0.0068 0.0070 0.0072 ;

0.0233 0.0236 0.0239 0.0243 0.0247 ;

1.5367 1.5125 1.4787 1.4317 1.3691 ;

0.0396 0.0413 0.0428 0.0441 0.0452 ];

In the above matrix for all columns the maximum value is present in the fourth row.

I want to shuffle the values in each column such that no two columns should contain the maximum value at tha same place.

could anyone please help me on this.

How are you defining 'shuffle'? Do you want them to retain their ordering, but in a circular shift down each column or is a random ordering fine so long as the max value is in a different row for each column?

[jaah navi]

The place of the values in each column can be randomly shifted under the condition no two column should contain the maximum values at the same place.

If I am understanding your problem correctly you could do something like this:

% define matrix of value
A=[0.0037    0.0036    0.0034    0.0033    0.0032    ;
    0.0064    0.0066    0.0068    0.0070    0.0072   ;
    0.0233    0.0236    0.0239    0.0243    0.0247   ;
    1.5367    1.5125    1.4787    1.4317    1.3691    ;
    0.0396    0.0413    0.0428    0.0441    0.0452   ];

% find current row number where each column maximum occurs
[~,idx] = max(A)

% define a random permutation which will give the new row locations of the
% maximum for each column
numColumns = size(A,2);
inew = randperm(numColumns);

% calculate required shift to achieve the new pattern
iShift = inew - idx;

% make new shuffled matrix
Anew = zeros(size(A)); % preallocate
for k = 1:numColumns
    Anew(:,k) = circshift(A(:,k),iShift(k))
end
