user input into simulink model

Hi,

I want to provide input to simulink model which has function block. How do I provide input such that when the model is run it ask the user to input values?

eg. in regular script we have for example,

X = input('Enter the value of X=');

So I want to have this incorporated in simulink model design or inside function block like-

if true
function y = fcn(w, X)

X = input('Enter the value of X=');

.... ....

end

I tried From workspace but could not get it work

Thanks

Model Callback Functions

[Suma]

hi,

thanks i am looking at this feature

are callbacks also used for doing loop operation for simulink simulation?

until now i have managed to build a source which outputs single random value and other function blocks acts on this.

i wanted to generate k values source data and each function block acts on them

for example in script we have, suppose x = rand

then i wanted for k = 1:10

y(k) = some_function(x(k))

How do i incorporate loop in my simulink model with each function block acting on each source output from k = 1:10

do we use callback function here too or we use other methods?

how can i implement this?

thanks a lot

hi,

i looked at the call back function, but it was difficult for me

i put X = input('Enter the value of X='); in various function call but could not stop execution thereafter, i also looked for examples but could not find suitable one

could anyone share illustrative example

thanks
