I want to obtain a vector as an input whit some value for each month of the year. So i did this way

    while true %January [kwh]
            TECJan=input("Feb [kwh] ");
            if isnumeric(TECJan)
                break
            end
        end
        
         while true %February [kwh]
            TECFeb=input("Feb [kwh] ");
            if isnumeric(TECFeb)
                break
            end
        end
         while true %March [kwh]
           TECMar=input("Mar [kwh] ");
            if isnumeric(TECMar)
                break
            end
         end
         while true %April [kwh]
           TECApr=input("Apr [kwh] ");
            if isnumeric(TECApr)
                break
            end
         end
         while true %May [kwh]
         TECMay=input("May [kwh] ");
            if isnumeric(TECMay)
                break
            end
         end
         while true %June [kwh]
         TECJun=input("Jun [kwh] ");
            if isnumeric(TECJun)
                break
            end
         end
         while true %July [kwh]
          TECJul=input("Jul [kwh] ");
            if isnumeric(TECJul)
                break
            end
          end
         while true %August [kwh]
   TECAug=input("Aug [kwh] ");
            if isnumeric(TECAug)
                break
            end
         end
         while true %September [kwh]
 TECSep=input("Set [kwh] ");
            if isnumeric(TECSep)
                break
            end
         end
         while true %October [kwh]
                      TECOct=input("Oct [kwh] ");
            if isnumeric(TECOct)
                break
            end
         end
         while true %November [kwh] 
                      TECNov=input("Nov [kwh] ");  
            if isnumeric(TECNov)
                break
            end
         end
         while true %December [kWh]
                      TECDec=input("Dec [kwh] ");
            if isnumeric(TECDec)
                break
            end
         end 
         
    TEC_Mm=[TECJan,TECFeb,TECMar,TECApr,TECMay,TECJun,TECJul,TECAug,TECSep,TECOct,TECNov,TECDec];
    
    

It works for me, but i was wondering if ther is an easy way , for example ask directly for vector elements as inputs, whit the possibility to ask only one time the whole elements of TEC_Mm

Such inputs are obtained using a GUI usually. The callbacks of the edit fields control the type of the input.

A loop would be easier also:

TEC_Mm = zeros(1, 12);
Name = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];
for k = 1:12
   while true
     tmp = input(Name(k) + " [kWh] ");
     if isnumeric(tmp) && isscalr(tmp) && isfinite(tmp)
         TEC_Mm(k) = tmp;
         break
     else
         fprintf(2, 'Bad input. Please repeat:\n');
     end
   end
end

Alternative:

while 1
    fprintf('Please input 12 values separated by spaces in kWh');
    tmp = input(" ", "s");
    TEC_Mm = reshape(sscanf(tmp, "%g "), 1, []);
    if isnumeric(TEC_Mm) & isequal(size(TEC_Mm), [1, 12]) & all(isfinite(TEC_Mm))
        break
    else
        fprintf(2, 'Bad input. Please repeat:\n');        
    end
end
