::DRAWING TWO SIGNAL ::need converter

[mangood]

Hi 

I just need to draw 2 signals at same time with index x range [-1.....1] with 0.1 step

the first signal is tan hyperbolic(x)  function and the second signal is my function(x) 

I think that I need a converter !!

First of all, there's a tanh(x) function in straight LabVIEW code.  Look in the Mathematics->Elementary & Special Functions->Hyperbolic palette.

Other random things:

1. There's a while loop that is running once.  The loop is not needed.
2. You have a bunch of boolean "Equal to TRUE" in there.  Also not needed.  Just pass the boolean through.
3. Do not wire the N for the FOR loop.  Let the autoindexing take care of the number of cycles.  Use the Array Size to get the number of samples are used.
4. You probably want to autoindex the output of your FOR loop in order to get your waveform.
5. Instead of the case structure to choose between 1 and 0, use the Boolean to (1,0) function.  It's in the Numeric->Conversion palette.

I did some  change to design as you said crossrulz 

the tanh has been drawn OK

but my function its input always ::21#;; why this?? This make my compactor output for entire loop true

I just need range of x -1 to 1 that enter my function

for each of value of x must  stay in loop 2000 times then out from my function that all what i want to do

can any suggestion

regards

Your VI did not change.  Did you upload the wrong copy?  Didn't save before uploading?

As far as the "::21#", is this with highlight execution that you are seeing this?  That would make sense.  The highlight execution shows the size of the array, not the data in it.

Each value must iterate 2000 times?

yes i uploading another one here that is simple

i did not know that.

yes every value of x must enter the loop 2000 times then go to graph

i want to compare the result of my function with tanh function with range of input from -1 to 1 by use graph

thank in advace

I cleaned up your code some, eliminating some duplicate code, initializing the feedback nodes when the loop starts.

I don't understand the purpose of the random number.  I would think that would cause nothing but error.

Dear  crossrulz

thank a lot.
My is function based on markov chain so with out this random the function will not work

I expect this error .

I want to draw the ideal tanh with my function at same time to see the error like below with x

Something like this?  I simply just called the VI made easier in a FOR loop, autoindexed the outputs, and created the graph plots.

okkkkkkkkkk

take this from me  for your help
