You should consider an alternative approach to this problem. Creating variables dynamically is a common and frequent source of errors. Additionally, it is a slow process.
Although the eval function is very powerful and flexible, it is not always the best solution to a programming problem. Code that calls eval is often less efficient and more difficult to read and debug than code that uses other functions or language constructs.
Please refer the following documentation link for more details:
One of several alternative approaches could be to use structures.
function S = eingabe_mehrerer_punkte( )
s = 'a':'z';
S = [];
for ns = 1:length(s)
point=input( 'specify a point: ');
S.(s(ns)) = point;
question = input( 'next point (j/n) ?', 's' );
if( question == 'n')
break
end
end
Then you can call the function as:
>> char_struct = eingabe_mehrerer_punkte( )
This would return the structure "char_struct" with the fields as consecutive alphabets.
