i want to change [3,2,4](1x3 matrix) to 324(1x1 matrix) any help?

i know i can do it by 3*100 + 2*20 + 4 but is there any cleaner method?

Answer 1

[Guillaume]

polyval(yourvector, 10)

would also work

But what if your vector is [30, 20, 40]?

[Hassaan Riaz]

mine values will be ranging from 0-9. Thanks

>> str2double(char([3 2 4]+'0'))

ans =

   324

This one produces NaN for overflowed data

>> polyval([3 2 4],10)

ans =

   324

>> str2double(char([3 2 10]+'0'))

ans =

   NaN
