Here are some miscellaneous helper programs for GuidedTrack. Enjoy!
Checks if an email address is valid.
Checks if matrix is a matrix (i.e., a non-jagged 2-dimensional collection). If it is, then is_a_matrix will be set to "yes"; otherwise, it will be set to "no".
Checks if vector is a vector (i.e., a 1-dimensional collection). If it is, then is_a_vector will be set to "yes"; otherwise, it will be set to "no".
Checks if collection contains only numerical values. If it does, then contains_only_numbers will be set to "yes"; otherwise, it will be set to "no".
Given vectors or matrices a and b, it computes the dot product of a and b and stores it in c. Optionally, a and/or b can be transposed prior to computing the dot product by setting should_transpose_a and/or should_transpose_b to "yes".
Returns the transpose of matrix as matrix.
Given start, stop, and (optionally) step values, returns a collection called range in the range [start, stop) in which each value is separated by step.
Given error_title and error_message, it shows a red error message box. By default, the error is fatal; i.e., the program will halt (but not quit) when the program is invoked. However, to invoke the program in a non-fatal way, set error_is_fatal to "no".
Given info_title and info_message, it shows a blue info message box.
Given success_title and success_message, it shows a green success message box.
Given warning_title and warning_message, it shows a yellow warning message box.
