Array with Complex Numbers

[mnwooddog]

I am attempting to export an array with complex numbers in the form x+yi to a txt file. We need this form as opposed to two columns with separate values because MATLAB needs it in the form x+yi. Right now it is only writing the x value to the txt file. Do I maybe need to change the format for Write Delimited Spreadsheet? Any suggestions would be appreciated.

I'd use Complex to re/im and format it manually, but there might be some hidden gem that automates that. 🙂

Hi mn,

as you forgot to attach your VI we cannot tell you what you did wrong!

For me it works as expected:

As you forgot to attach your VI we cannot see the coercion dot in your code which warns you about (unexpected?) datatype conversions…

GerdW is close.  You just have to search and replace the SPACES with NOTHING  Matlab hates the dang space as I recall.

I've attached the VI (but it's very convoluted with everything we're doing, so I've also attached a screenshot on the area I'm focused on).

I will give your method a try. I've replied to my original post with the VI and a screenshot of the specific area I'm addressing

See that ugly red colored dot on the orange wire?  That is where your Complex Double is Coerced to Double

Oh, I see! How do I fix that?

How would you then output your spreadsheet string to a txt file? How I have it set up now there is an output of Build Path connected to an output of Array to Spreadsheet String.

When I want to write strings to a textfile then I use a simple WriteTextFile function.

Sounds very logical to me…

Again you forgot to attach your VI so we cannot tell you what you did wrong in your VI…

But how do you connect the output of one function to the output of another function???
