Advanced getting matrix element

Rainbow claw 10 Feb 2020 13:04

Hi, I was attempting to get a specific matrix element using the normal methods (eg. [A](1,1) to get element in 1st row and column), however as soon as I add any calculations into this, I get a syntax error. For example, attempting to do

`(2[A])(1,1)`

will result in a syntax error. I was primarily trying to use this within the graphing part of the calculator by describing a function of ([A]

^{x}[B])(1,1) in order to get the 1st row and 1st column of the resulting vector however this neither worked in the graphing app nor the main calculations section
