How do I make a 10x10 showing all numbers 1 to 100?

how do i create a nested loop tht will provide me with a 10x10 matrix with all the numbers 1 to 100 like this

1 2 ... 10

11 ... ... ...

... ... ... ...

... ... ... 100

@Patrick Duffy: what have you tried so far? Is it a strict requirement to use nested loops?

Following code will create a matrix as stated above:

x=reshape( 1:100, 10, 10).';
%1:100 will create a linear matrix with 1 to 100 as elements
% reshape will convert the 1 to 100 matrix into 10*10 form
% .' will do transpose of it

X will contain the required result

175 times faster using implicit expansion

y = (1:10:100)'+(0:9);

Each point below is the runtime of 10000 iterations using the reshape method (red) and the implicit expansion method (blue) which was repeated 50 times (x-axis).

• reshape mean: 0.0151 sec (10000 iterations)
• implicit expansion mean: 8.6220e-05 sec (10000 iterations)
