Difference in evaluation of two exponential expressions

Version: 3.x - Scientific WorkPlace & Scientific Notebook

If A is a matrix, then an evaluation of Math: exp(A) results in Math: exp(A)=e (superscript A), rather than the requested computation. Evaluation of Math: e (superscript A) results in the requested computation. The intermediate step seems unnecessary since it results in only different notation instead of evaluation.

However, Math: e (superscript A) and Math: exp(A) are parsed differently. When Math: exp(A) is parsed, the software doesn't check for matrix exponentials. When Math: e (superscript A) is parsed, the software does make this check.
