Index of matrix element in Matlab

[tombraided]

Hi there...

I have a matrix as:

a = [1 3 2 6 8 9 6]

can anyone tell how I would be able to get the index of the element(s) for 6. Here the answer should be [4,7]. It should be in matlab.


Thanks in advance.

I don't understand how you came up with [4,7].

Anyways, there is command ind2sub for that. And to go backwards sub2ind.

Hope this helps

a = [1 3 2 6 8 9 6];

if you want to get the index of the element(s) for 6, you should type with the following command

find(a == 6)

Therefore, the answer is 4 and 7

ps. I use matlab version 7.6 (R2008a) with the above command.
