Matrix with variables

[amandabrooke93]

How do you enter a matrix with variables into the HP Prime. Such as with i, j, k. Please include very detailed instructions. Thank you!!

Use the CAS mode for symbolic content. The variable i is a reserved variable for imaginary numbers.

[CAS]
m:=[[x,y,z],[x+2,j+y,k*x+2]];

Copy the matrix m (above), and enter it into the command entry line. You can paste it in, if using the emulator, or manually enter it if you are using the hardware calc.

Be careful with variables! The reserved variables work as designed, and which may not work as you might, otherwise, expect. Things like [Home] reserved variables get evaluated to their current value after entry, and won't show up symbolically in your matrix, directly. Using the matrix variables M0-M9 as matrix names, will expect real number entries. It's a good idea to use lower case variables in [CAS], and upper case variables in [Home]. This is very general information, and hopefully useful for you.
