[mjalali-2]

hi

for example if A=(a,b,c,d,e) and a=1, b=-3, c=4, d=2, e=-1,

how can I choose "d"(minimum positive number biger than one)

"A" is matrix

thanks alot but I want to choose only from real number not from Imaginary numbers

Maybe that way:

But using the built.in functions match and trim you get into troubles if all values in A a bigger than 1.

Solution can be to write a program for your task or rewrite match and trim to work even if nothing has to be trimmed.

In this case you need to use "match ()" built-in function:
