Issue with examples in new function corr in the parser

[dvd101x]

Hi, I was checking on the new function corr to see how it works and found the following while typing help(corr) in the Demo

corr([2, 4, 6, 8], [1, 2, 3, 6])
# yields TypeError: Unexpected type of argument in function matrix (expected: string or Array or Matrix or boolean, actual: number, index: 0)

It works correctly by adding a dimension:

corr([[2, 4, 6, 8]], [[1, 2, 3, 6]])
# yields [0.95618288746751]

Nonetheless outside the parser it works as expected regarding if it's a 1D array

math.corr([2, 4, 6, 8], [1, 2, 3, 6])
// yields 0.9561828874675149

Also noticed that the second example includes the function matrix which is by default in the parser.

corr(matrix([[1, 2.2, 3, 4.8, 5], [1, 2, 3, 4, 5]]), matrix([[4, 5.3, 6.6, 7, 8], [1, 2, 3, 4, 5]]))
# yields [0.95699416885036, 1]

So this could also work with a bit of simplification.

corr([[1, 2.2, 3, 4.8, 5], [1, 2, 3, 4, 5]], [[4, 5.3, 6.6, 7, 8], [1, 2, 3, 4, 5]])
# or
corr([1, 2.2, 3, 4.8, 5; 1, 2, 3, 4, 5], [4, 5.3, 6.6, 7, 8; 1, 2, 3, 4, 5])
# yields [0.95699416885036, 1]

The function corr is really cool, just wanted to let you know of these issues in the parser.

Thanks for bringing this up. So it looks like corr does not yet support a Matrix with 1d contents, like:

math.corr(math.matrix([2, 4, 6, 8]), math.matrix([1, 2, 3, 6]))

The second example indeed doesn't add much, maybe better to remove it.

@vrushaket would you like to refine the function corr a bit?

[vrushaket]

@josdejong yes, i will make necessary refinement.

Thanks!

Since #3030 has been merged, can this be closed?

[josdejong]

O, yes, you're right. Closing it now.

I'll post a message when the fix is published, that's not yet the case.

The fix is published now in v11.11.2
