pole zero surface plot for read 1D data ( number of data 700)

[laplace_transform]

I like to go for laplace transform of 1D real data (number of data 700) and pole zero surafce plot for showing peak of poles.

Can anybody help me,

Thanks

Do you already have your 1D array of data?

There is a Laplace transform function here:

 Signal Processing >> Transforms >> Laplace Transform Real.vi

It takes an input of a 1D array of data, and 'end'.

End is the time of the last point.

(ie initial time t=0, end t=X)

It will then output an array of transformed data.

Hello cory:

After laplace {x}, how can suface of abs(laplace {X}) whic will give me pole zero peak in 3D  surafce ( s palne).

Thanks

Can you please elaborate on what you are trying to do?

Once you used the Laplace Transform, you would like to plot this value on a surface plot?

If that is what you are asking:
A 3D surface plot takes inputs of an x-vector, a y-vector, and a z-matrix.

The z-matrix would contain the transformed data.

Hello Cory:

You said to write elaboratly. Thanks.

After laplace transform I get Laplace {X}. This is an array,  say 500 data. they are alll real.

According to the laplace transform rule, I can plot pole and zero in s plane. My intention to plot pole and zero in the s plane.

I dont know how I can plot pole and zero from laplace{X} real data.

Your help would be greatly appreciated.

Thanks
