Gilles commented on MATH-858:
-----------------------------
Which version of Commons Math are you using?
In the current development version, this code:
{noformat}
BlockRealMatrix correlationMatrix = new
PearsonsCorrelation().computeCorrelationMatrix(data);
{noformat}
does not even compile.
When you report a bug, please provide a fully working minimal code example.
Could you also provide the stack trace of the exception?
Moreover I cannot find any Commons Math error message that contains the string
"mismatch between indexed read"...
> BlockRealMatrix java.beans.IntrospectionException
