I'm trying to set up code that basically asks the user to input the values of a matrix with a certain key size. I want them to first enter the keysize and then ask for all of the entries necessary to fill the square matrix of that keysize.

  • $\begingroup$ Mathematica has already provided means to input a matrix. See e.g. reference.wolfram.com/language/howto/InputAMatrix.html $\endgroup$

  • $\begingroup$ After you ask for the matrix size, you could present a TableView using the matrix size for the AllowedDimensions option. $\endgroup$

This is not an answer. This Code may help you prepare your input boxes.

Panel[
country = 0;
sector = 0;
level = 0;
result = {};
While[Not[IntegerQ[country] && 1 <= country <= 64], (country = Input["Which country do you want to analyze?"])];
While[Not[IntegerQ[sector] && 1 <= sector <= 15], (sector = Input["Which sector do you want to target?"])];
While[Not[NumericQ[level] && 0.01 <= level <= 1], (level = Input["At what significance level do you want to analyze IO matrix?"])];
result = {country, sector, level};
If[
 result === {}, "", result
 ]
]

    $\begingroup$ This hangs up Mma 12.2.0-Win7x64 and the dialog wouldn't go away. Perhaps it is a version related artifact. There is a comma flagged in red in the If statement at the end. $\endgroup$

    $\begingroup$ is result === {}, "", to be result === {}, "", result ? $\endgroup$

  • $\begingroup$ @AsukaMinato: Yes, you are right, however, for some reason, the dialogue box does not go away as noted by Syed noted. I cannot find the reason for that. $\endgroup$
