176 Section 12: Calculating with Matrices

Using Matrix Operations in a Program

If the calculator is in User mode during program entry when you enter a

O or l{A through E, %} instruction to store or recall a

matrix element, a u replaces the dash usually displayed after the line

number. When this line is executed in a running program, it operates as

though the calculator were in User mode. That is, the row and column

numbers in R

and R

are automatically incremented according to the

dimensions of the specified matrix. This allows you to access elements

sequentially. (The USER annunciator has no effect during program

execution.)

instruction  when R

and R

are returned to 1  program execution skips

the next line. This is useful for programming a loop that stores or recalls

each matrix element, then continues executing the program. For example,

the following sequence squares all elements of matrix D:

1 2 ... 171 172 173 174 175 176 177 178 179 180 181 ... 287 288
