Row operation on array with a For Loop

[quasarman]

Hi,

I'm working with a large one dimensional column array. I'm trying to do the following

for i=1:size(A)/2

B(i,: ) =A(1+(i-1)*2:i*2)

So, for example if

A=          

0

1

2
3
4
5
6
7

then

B=             

0 1

2 3
4 5
6 7

My approach was to use an array subset block inside the for loop to select a number of elements but I'm not sure how to transpose the selected elements into a new row to create the new array B. Is there a more straightforward approach?

Thanks,

Mike

try experimenting with the reshape array feeding it your input array and re-sizing it to output a 2d aray. It is much faster than using a For loop becuase the data never gets moved and LV just changes the array dimensions and updates the stride.

Thanks, I tried it with reshape and its much easier.
