How to determine the position of an integer

Hi,

I have a very basic question. I have a variable containing 5 numbers, say for eg,

d= [1 4 3 2 5]

how can i find the position of the number 3 in this d. I tried to use Find but I think I am using it wrong . Can anyone help me out please.

Thanks,

Vivekram

If you want to use the find function:

pos = find(d==3);

Hi Robert,

Ya , I tried it out but unfortunately the values are in cell format. Thereby giving me an error saying:

Undefined function or method 'eq' for input arguments of type 'cell'.

Can you suggest a way?

Thanks

Hi Vivekram,

I'd sugget using the "unique" command

[C, ia, ic]=unique(d)

ic will give you the indices of the numbers in your array d

Hi Jim,

How will it give me the position of the digit 4 only? and the other thing that I forgot to mention is that the values are in a cell format.

Thanks

If the values are in the cell format use cell2mat function:

pos = find(cell2mat(d)==3)
