Invalid Matrix Token

Hi. I didn't find anything about this beside <https://community.jmp.com/t5/Discussions/invalid-matrix-token/td-p/2111> (a terribly formatted post) and nothing in the Scripting Index. What is an "invalid matrix token" error? What does it mean?

 

When I try to instantiate a matrix in my script like

m = [i j];

where and are numerical variables, it throws the error and points at i.

 

I think that's all the context I can give. Let me know if any clarification specifically is in order, I can try to help you help me.

 

Cheers,

Mike

ScriptingRe: Invalid Matrix Token

Cannot exactly explain the error message. Most likely related to this Construct Matrices and in the end:

Construct Matrices from Expressions

To construct matrices from expressions, use Matrix(). Elements must be expressions that resolve to numbers.

 

Names Default To Here(1);
i = 1;
k = 1;
m = Matrix({{i, k}}); //[1 1]

 

 

Re: Invalid Matrix Token

Thanks, @jthi. That works!

 

Can you comment briefly on dimensionality? I think I figured it out, {{}{}} is a 2x0, but I don't know how to make a 0x2.

Re: Invalid Matrix Token

Play around with this example:

Names Default To Here(1);
i = 1;
k = 1;
m1 = Matrix({{i, k}}); //(1x2)
m2 = Matrix({{i}, {k}}); //(2x1)
Show(m1, m2);

and check the Construct Matrices From Lists from the link I provided earlier.

 

Re: Invalid Matrix TokenI am having trouble concatenating using Concat() or |/ my starting array and additional elements. When I Write() the output, it is equivalent to the starting array, nothing was concatenated (result is [0 0]).
