for example i have a vector with variables, and my list of statistics are min,max,mean,median and std. i need to write a function that will help me choose 3 out of the given list of statistic and represent on a script.

i need to use the elseif statement to choose any of the statistic that will be entered as an input in the command window

No you don't. If you want 3 (or any number) to be executed, you want to have 3 independent if statements with NO elseif.

Is this your homework? http://www.mathworks.com/matlabcentral/answers/8626-how-do-i-get-help-on-homework-questions-on-matlab-answers

Hi Brenda,

function choose3(a,b,c)
simplevar = [1 2 3 4 5 6];
a = string(a);
b = string(b);
c = string(c);
if ~isstring(a) || ~isstring(b) || ~isstring(c)
    error('Your input is not compatible'); 
end
if strcmp(a,'min')==1 || strcmp(b,'min')==1 || strcmp(c,'min')==1
     fprintf('the minimun is %d \n',min(simplevar));
elseif strcmp(a,'max')==1 || strcmp(b,'max')==1 || strcmp(c,'max')==1
     fprintf('the maximun is %d \n',max(simplevar));
end
end
