Reordering columns of two dimensional matrix

[renault]

Hello all,

How to reorder the columns of a two dimensional matrix as per the conditions given below

1. The front panel should contain a string  control. when supplied a list of indices of column  in  the string control. The ordering of the columns should be done according to the order list provided .

2. when  0s are entered in the string control ,  column values of that index should contain 0s.

 please provide a solution or VI  for this . regards

Hi Have you tried Array->reshape Array?

I think this VI (7.0) will do what you mean - it creates an array the same size of the original and extracts the columns from the original.

2 points -

• 0 is a problem because in LV (like many other computer languages), 0 is the first element. -1 will do what you wanted instead.
• This assumes space as a seperator between the values in the string. You may wish to have a 1D numeric array instead of the string.
