Something like this. With Matlab it's common practise to use double for all numerical variables. (Matlab has "integer in floating-point format" called flint, which isn't affected by round-off errors. See Floating Points in Matlab.)
A = rand(100,100);
Fill_Value = int16( 0 );
ten = int16( 10 );
Shift_value = int16( ?? );
A = noncircular_shift( A, Fill_value, Shift_value, ten )
where
function A = noncircular_shift( A, Fill_value, Shift_value, ten )
for Target_Group = 1: +5: length(A)
for Relative_Row = 0: 4
Row = Target_Group+Relative_Row;
Shift_Value = Relative_Row* ten ; % notice ten
A(Row,:) = [Fill_Value*ones(1,Shift_Value), A(Row,1:end-Shift_Value)];
end
end
end
Notice that the loop-counters will be doubles (i.e flints).
