Tips on how to input matrix ?

1: Input matrix starting from the upper lefthand corner.

Example: To input matrix: $ \left[ \begin{array}{cc} -7 & 1/4 \\ -1.3 & -2/5 \end{array} \right] $ type

2: You don't need to enter zeros.

Example: To input matrix: $ \left[ \begin{array}{ccc} 0 & 1 & 0 \\ -1 & 0 & 0 \\ 0 & 0 & 2/3 \end{array} \right] $ type

3: You can copy and paste matrix from excel in 3 steps.

Step 1: Copy matrix from excel Step 2: Select upper right cell Step 3: Press Ctrl+V

4: You don't need to use scroll bars, since the calculator will automatically remove empty rows and columns.

5: To delete matrix

Select whole matrix and click delete
