Hello all, I am having confusion with the IF statement because I have seen that in other languages there is ELSEIF or ELIF, and when searching for something similar in Mathematica didn’t find it, it is for this reason that I am turning to you to ask them if there is something similar to ELSEIF or ELIF or definitely should i use WHICH, I share with you some images of what I am talking about. By its aid, a thousand thanks,greetings
HERE IN MATLAB
Which is essentially synonymous with an elseif construct in other languages. This should probably be clarified in the documentation. If you want to add a final else statement, set the last condition to True, like this:
In[1]:= x = 5; Which[x == 1, 10, x == 2, 20, x == 3, 30, True, 100]
Out[1]= 100
If you want to test different patterns against a single value, Switch might be more elegant. See below:
x=2;Which[x==1,10,x==2,20,x==3,30]
is the same as
Switch[x,1,10,2,20,3,30]
but the latter looks better.
If can be nested. That makes it semantically equivalent to “elseif”, but there is the syntactic burden of matching more closing right brackets.
Many thanks to Daniel Lichtblau and Jesse Friedman for their replies, the problem i have is that I do not know how to move from what is done in Modula-2 to Mathematica, i.e. i have problems to separate it into parts to do so using WHICH the other is made and verified. If someone can help me appreciate greatly.
Annex in a document the code that i have Modula-2 and also the translation attempt to Mathematica that i made. What causes me conflict is the ELSIF , because I do not know how to have fun to Which
Thanks in advance.
