The TI-86 distinguishes
between uppercase and
lowercase letters in matrix
names. For example,
MAT1
and mat1 are two different
vector names.
Matrices on the TI-86
A matrix is a two-dimensional array, arranged in rows and columns. The matrix elements
can be real or complex. You can create, display, and edit matrices on the home screen or in
the matrix editor. When you create a matrix, the elements are stored to the matrix name.
