Hi everybody:

Some tiem ago I tried to assemble a matrix, but I only encounter the augment command, How can I to stack matrixes?

I appreciate some help.

Thanks for your answer!

Well, when I say stacking matrixes I mean that should exist a function thst "stacks" as supporting "augment" function, with the augment function we put a matrix A2 [m x n] aside A1 [m x n], a stack funtion should puts the matrix A2 [m x n] below A1 [m x n]. Executing a line like [[1,2],[3,4]] => A, only stacks vectors not matrixes or not?

?Does exists some function that make that in the Classpad? I hope so...


Thanks in advance.

Please describe clearer. By "stacking" and "assembling" matrices, you mean saving them? You can define a matrix and save it to the variable 'x' this way:

[[1 2][3 4]] => x
(Instead of "=>" put the ClassPad's arrow found in the first row of mth keypad.)

you can also use fill(value, lines, cols), it returns a lines * cols matrix filled with value

I don't think there is such function, but you can put A2' aside A1' (' = transpose) and the transpose the result.
