Instructions
Please enter a matrix whose values are not too big (less than 5) or too small (greater than .1) Otherwise you will have a difficult time interpreting the results. Note that the changes you have made do not register until you hit enter. The color blue will indicate that the value has not been fully entered.
Use your mouse to select the vector on which you want the matrix to operate. You can drag your mouse as well as click, but if you're not on a very fast computer, please drag slowly.
If you're experiencing technical difficulties using the applet please let us know. In your message please indicate your operating system as well as the version of your browser.
