Hi,
m = 3; c = [40,39,36,30,22,21]
I have to get the answer in matrixformat d= [40 39 36 ; 21 22 30] as my machine size m = 3
once the first row is over(3 elements are printed),remaining elements of c matrix has to be printed in reverse order as shown in second row of d matrix.
Advice me regarding

Reshape and fliplr will help you here:
m = 3;
c = [40,39,36,30,22,21,1,2,3,4,5,6]
result = reshape(c,m,[])'
result(2:2:end,:) = fliplr(result(2:2:end,:))
Note that there are some subtleties with how matrices are reshaped that are a result of the column-major nature of MATLAB. This is why the transpose is there. Read the reshape doc for more info
