Abstract
A calculating apparatus comprises a memory and a calculating section. The memory is stored with table data for referencing a value of a variable x by using a value of a variable y and a value of a solution z. The calculating section inputs x_in and y_in, reads two values y_a and y_b corresponding to y_in from the memory, reads two values x_aa and x_ab corresponding to x_in from the memory in a line corresponding to y_a, reads two values x_ba and x_bb corresponding to x_in from the memory in a line corresponding to y_b, and calculates a solution z corresponding to x_in and y_in in an interpolation by using x_in and y_in and the read values y_a, y_b, x_aa, x_ab, x_ba, and x_bb.
Claims3
A calculating apparatus for calculating a solution z by using a variable x and a variable y, comprising:
- a memory for storing table-format data for referencing a value of said variable x by using a value of said variable y13 and a value of said solution z;
- and
- a calculating section, which:
- inputs a given value x13 in of said variable x and a given value y13 in of said variable y and reads out two values y13 a and y13 b of said stored variable y13 corresponding to the given value y13 in of said input variable y13 from said memory;
- reads out two values x13 aa and x13 ab of said stored variable x corresponding to the given value x13 in of said input variable x from said memory in a line corresponding to said value y13 a of said table-format data;
- reads out two values x13 ba and x13 bb of said stored variable x corresponding to the given value x13 in of said input variable x from said memory in a line corresponding to said value y13 b of said table-format data;
- and
- calculates the solution z corresponding to the given value x13 in of said input variable x and the given value y13 in of said input variable y13 in an interpolation by using the given value x13 in of said input variable x, the given value y13 in of said input variable y, and the read values y13 a, y13 b, x13 aa, x13 ab, x13 ba,and x13 bb.
