Thread Subject: position in a vector

Hello everyone
I have a question let say you have a vector
x=[5 1 8 2]
And you want to specify the location (indice) of any number in that vector
 For example you want the position of the 8 the output of the program should be 4.
Any suggestions
thanks

Shouldn't the position of the 8 be 3, not 4? Here is one approach, with the usual FP warnings:


pos = find(x==8)

yessss your right im sorry and yes it works thanks alot :)

Dear halee!

> pos = find(x==8)

Sometimes faster - and working for double vectors also inspite of the name:
  pos = findstr(x, 8)
