Is it possible to lock or fix an input value given by the user, inside a for loop?

dt=input('time differential = ')
segeval=input('seconds to evaluate = ')
nn=ceil(segeval/dt)
func(nn,1)=zeros
t(nn,1)=zeros
cont=0
for i=1:nn
     t=cont
     funcion=input('What function with respect to "t" do you wish to evaluate ')
     func(i,1)=funcion 
     cont=cont+dt   
end   
     % this is the function in this case 10*sin((pi*t)/0.6)

This code works in evaluating the function at each different value of "t" but the problem is that, since it is in the for loop it asks the user every cycle for the function again. Any idea on how to lock it in??

Ask for the function first, before you enter the loop.

在 MATLAB Online 中打开

dt=input('diferencial de tiempo = ')
segeval=input('segundos a evaluar = ')
nn=ceil(segeval/dt)
func(nn,1)=zeros
t(nn,1)=zeros
cont=0
for i=1:nn+1
     t(i,1)=cont
     cont=cont+dt   
end   
    funcion=input('introducir funcion de carga con respecto a "t" ')
       % 10*sin((pi*t)/0.6)
