I have 2 vectors that I would like to correlate with one another: OptimismBias and AmbigTolG (listing the first 10 values out of 248).

-0.0263 0.0000

0.7971 0.0000

-0.2800 -0.0000

0.4088 0.0000

0.6691 0.0000

0.5348 NaN

0.2606 0.0000

0.6995 NaN

-0.3270 0.0000

0.4665 0.0139

When I run the corr, I get all NaNs at the output. I'm aware that the AmbigTolG values are 0 or close to 0 but I'm not sure how else to run this.

You can use

corr(OptimismBias, AmbigTolG,'rows','complete')

to ignore the NaN values.
