Abstract
An electronic device for calculating and displaying a matrix of the invention includes a display having a screen portion for displaying a matrix, and a keyboard by which commands are input into a CPU. After receiving a matrix generating command from the keyboard, the CPU controls a display of the matrix in a row-column format in which each element of the matrix has an initial value. The CPU further receives values of elements of the matrix from the keyboard. One of the elements the value of which is to be changed is designated by a cursor on the screen portion.
