Entering Matrices

The process of entering matrix in gcalcrpn is simple. First select the matrix button from the main screen as seen below.

Creates a new pop-up window where you can choose to enter a new matrix or perform a matrix op.

Choose to enter a new matrix and you will be shown a screen where you can enter the size of the matrix

After you enter the size of the matrix gcalcrpn creates a mini-spreadsheet the size of your matrix for you to enter the matrix. Enter the matrix here and press OK when you are done.

Pressing OK here will place the matrix on the stack!! pressing cancel at any time in this process will just abort the process and return you to the main window. gcalcrpn now supports entering entering more complex expressions into matrices. simply put $3/5$ or $(1+2/7)/(3-4/3)$ into the entry and gcalcrpn will evaluate the statement into a floating point number.

You can also enter matrices into the inport field. to do this use a matlab style command like $[1, 2; 3,4]$. Make sure that you use the comma's or the parser will not understand what you mean!!
