Hallo guys i have a problem and i dont know how to write it in smath.

for example:

i have a variable and i want to assign certain values depending on other values.

for example:

Variables:

a=1
b=2
e=1 or 2 for example

and now:

c:= a if e=1
b if e=2

and then

OK if c=1
NOK if c=2

also i can remember the function sverweis in mathcad to assign certain values to a variable out of a matrix

i dont know how to write in smath
i know its easy example but its only for demonstration

I know how to write in mathcad but not in smath
thank you br Stefan

just trying. I think i got it but is there a better way to assign such values?

I just want to do it with if only

So that

e:= if a=1 then e=10
if a=2 then e=11
if a=3 then e=12
if a=4 then e=13
if a=5 then e=14
if a=6 then e=15

like this way

and so on not with if else if else is a little bit confusing

thank you best regards stefan

thank you but im having troubles writing this code.

How you write the if without else and how do you write the otherwise

i see no otherwise and i always have the if with else statement

or do i need a plugin for your function?

thank you

i now encounter another problem. If i have many decisions how can i align the variables vertically?

I have not enough place on the sheet so that every variable can stay there in one row

like in the sheet

not with if else

Try if/otherwise from f(x) menu cases

Are you trying to achieve this?
It takes very little space on sheet.
You did mentioned vlookup function.
This gives a variable depending on a decision.
Or maybe I have lost in the context.

It is the function cases from custom functions plugin. To add more "if cases" you have to type twice your argument separator key.

If you like my plugins please consider to support the program buying a license; for personal contributions to me: paypal.me/dcprojects

You need to install Custom Functions plugin.
After you have installed Custom Functions plugin;
You can either enter it from menu, Insert > Function > Cases().
Or you can press Ctrl+E key combination and insert Cases().
Or simply type cases(), press Tab or click on it and will be added.
Last one is how most people insert it I guess.

Please don't hesitate to ask anything.
You will find out this is one of the most friendly forums on internet.
Everyone is eager to help and shall try to reply your questions.
