Hi!
I have matrix:
A = [(1:1:5); (-5:0.5:-3); (0:4); (10:-1:6); (2:2:10)]
%it gives me
A =
1.0000 2.0000 3.0000 4.0000 5.0000
-5.0000 -4.5000 -4.0000 -3.5000 -3.0000
0 1.0000 2.0000 3.0000 4.0000
10.0000 9.0000 8.0000 7.0000 6.0000
2.0000 4.0000 6.0000 8.0000 10.0000
% i want to see
A =
1.0 2.0 3.0 4.0 5.0
-5.0 -4.5 -4.0 -3.5 -3.0
0.0 1.0 2.0 3.0 4.0
10.0 9.0 8.0 7.0 6.0
2.0 4.0 6.0 8.0 10.0
My question is, is it possible to control the amount of decimals in the matrix? Can someone help me to understand this

You can control this with the fomat function. The closest you can get is two decimals with
format bank
You should be aware that how Matlab stores data and how Matlab displays data isn't very strongly linked.
You can use fprintf to display your data any way you like.
