APPARATUS FOR DISPLAYING MULTIDIMENSIONAL INFORMATION

In order to display the value of a multivariable function at at least one point around an arbitrary point which exists in a multidimensional space defined as a domain of the multivariable function, a display plane is divided into a plurality of regions, the plurality of regions are brought into correspondence with a plurality of quadrants which have the arbitrary point in the multidimensional space as a common vertex, respectively, and the value of the multivariable function at a point on the quadrant existent around the arbitrary point is displayed at the position of that point on the region which corresponds to the quadrantal point. The incremental or decremental situation of the values of the multivariable function around the arbitrary point in the multidimensional space can be visually expressed by a single plan view. The multidimensional information displaying method can be utilized for the verification of the result of an optimizing computation, and in turn, for example, for the optimum control of a system.
