I entered in column B(1): =A1 + 1, that is I added the value 1 for

They don't accept a value of -0.999 instead of 1, they just

Mind if I ask, in which file is the CORREL function defined?
Tests are still useful to see where the algorithm fails (and
purportedly, the new algorithm should be correct). Extensive test cases
are always welcome.

Calc uses indeed the *naïve algorithm* to compute the Correlation
Coefficient (see Wikipedia).

Nah.. there won't be more than 2^32 matrix elements..
OR is (unsigned int) count OK
size_t respectively SCSIZE is preferred instead for clear

1. I forget a count++; in the first for LOOP
[inside the: if (!pMat1-IsString(i,j) !pMat2-IsString(i,j)) {} body]
2. because this count would be from 1 to n, the 2nd for LOOP should be
modified accordingly:
for(j
