Correlation coefficients

returns
the matrix of correlation
coefficients for `R`

= corrcoef(`A`

)`A`

, where the columns of `A`

represent
random variables and the rows represent observations.

`[`

returns the matrix of correlation
coefficients and the matrix of p-values for testing the hypothesis
that there is no relationship between the observed phenomena (null
hypothesis). Use this syntax with any of the arguments from the previous
syntaxes. If an off-diagonal element of `R`

,`P`

] =
corrcoef(___)`P`

is smaller
than the significance level (default is `0.05`

),
then the corresponding correlation in `R`

is considered
significant. This syntax is invalid if `R`

contains
complex elements.

`___ = corrcoef(___,`

returns any of the output arguments from the previous syntaxes with additional
options specified by one or more `Name,Value`

)`Name,Value`

pair arguments.
For example, `corrcoef(A,'Alpha',0.1)`

specifies a 90%
confidence interval, and `corrcoef(A,'Rows','complete')`

omits
all rows of `A`

containing one or more `NaN`

values.
