I have values of different loads and N1 values .Need to substract with row2-row1,row3-row1....like row1 was constant here.

Your statement is still quite unclear.

From what I have understood,

y=randi(20,4,5)
y = 4×5
     9    18     2     3    11
     6     6    12    18     8
    18    18    19     9    10
    17     1    20    13    11
for i=2:size(y,1)
    z=y(i,:)-y(1,:)
end
z = 1×5
    -3   -12    10    15    -3
z = 1×5
     9     0    17     6    -1
z = 1×5
     8   -17    18    10     0
