Question: Tex error: 'The function ne() has been..'

Dear All,

I've just started using MapleTA and I'm exploring the Latex capabilities. The test question that I have constructed looks like:

\qutext{Test  \blank[formula]{\var{ans}} Test.}

However, I get the following error during latex conversion:

There is a problem generating randomized coefficients for this question:

Error initializing : There is a syntax error in the algorithmic expression "LinearAlgebra[MatrixInverse](Matrix([[1,2],[3,4]]))". The following error message was generated:

The function ne() has been called with the wrong number or type of arguments


Thanks for any help,


Please Wait...
