Taking individual values from an array
显示 更早的评论
P=[1 3 6 7 8] P1=P(1) P2=P(2) P3=P(3) P4=P(4) P5=P(5)
instead of using the above commands for taking individual values of P1-P5 from the array,need a simple command that can load data

Where you want to use the data, you can call it by using P(1) or P(2), etc using indices. What else you are expecting ?

@Bilal Khurshid: your choice is between indexing and dynamic string evaluation:
Indexing:
- simple
- fast
- easy to read
- best practice
- used by experts
Dynamic variable names:
- slow
- buggy
- difficult to debug
- used by beginners
Which one are you going to choose?

What you want to do is not suggested. Better you proceed with the matrix/ array itself.

Yes! Do not use numbered variables.
You have a very convenient way to access the Ps you want, it's called indexing. Any workaround that you may find will be slower, buggier, harder to read and certainly a lot uglier than a pair of parentheses.
