Q:
Can one change the title that a matrix displays?  Also is there a limit on the length?
A:
Yes.  To make this change type "<@ your new title" (without quotes) in the parser/evaluator and then depress enter.  If the title is more than two lines long it may ruin the print routine.

Q:
Does the registered version view larger matrices.
A:
The registered version keeps evolving in response to customer's  needs.  As of this writing one can view a single column matrix of 5000+ elements, a double column of 2500+ elements.  The largest square matrix at this point is still 64x64 but that will quickly change.

Q:
Can I input a matrix file created in Excel into MtrxCalc and vice versa?
A:
Yes you can now import (using the file menu and import command) matrices created in Excel and saved as csv-text files.  And ofcourse you can save matrices as text files also.  See the help files.

Q:
Is there some way I can perform different transformations on different columns of a matrix?
A:
In the latest version I can give partial yes.  You can use the col() function to extract a column, or simply start with column matrices and then when finished with the transformation concatenate them into a single matrix.  To perform the natural logarithm transformation on column matrix C use the apply() function as in apply(ln, C).  You can use apply() with any of the scalar functions supplied such as sin, cos,tan,...sqrt,abs,re() and etc. but unforunately functions square() & cube() are not provided in this demo but will be in the registered version.

Q:
I keep forgetting to save the matrix I am currently working with to some other name and then I lose it.  It's frustrating! Can't it be saved automatically?
A:
Not at present.  We are working on saving the current and the next previous but this is not yet ready.
