Use the buttons to perform functions accordingly. For instance, if you click "New" and then "Matrix" you will create a new matrix with a size you specify. If you click "Column" instead, you will create a new column in a matrix you select. Because matrices can be any size you want, big ones tend to go off screen. That's why I added scrollbars at the bottom and right edges. If you click on "/comm", you can enter code into the prompt. Syntax is okay as long as you enter in the correct info: Command + Object or Operation + needed input Commands ( / means it can be typed either way): new / create set / replace change multiply / scale delete / del operation / calculate / calc Operations (after putting the operation command): addition / add / + subtraction / subtract / - multiplication / multiply / * / x determinant / det inverse / invert / inversion / inv Objects for commands: matrix / m row / r column / c item / i Examples: "create matrix 5 by 3" // this is matrix 1 "create matrix 3 by 2" // this is matrix 2 "set matrix 1 to 3" // sets all values in matrix 1 to 3 "change matrix 2 by 7" // increases all values by 7 "change row 1 of matrix 2 by 4" // increases all values in row 1 by 4 "operation multiply 1 by 2" // multiplies matrix 1 by matrix 2 "operation 1 + 2" // adds matrix 1 and matrix 2 "operation 2 - 1" // subtracts matrix 2 by matrix 1
My old matrix calculator never got the updates it needed... until now. Complete with an almost full library of basic commands and infinite matrix generation, and scrolling too. :) Originally Shared 27 Nov 2012.
