<p>PROBLEM TO BE SOLVED: To simply and surely judge whether two mutually related variables have a certain fixed relation or not. SOLUTION: A projected or rugged polygon area is set up for two mutually relative variables, whether the variables are included within the area or not is judged and the judged result is outputted. Namely the polygon area consists of plural vertex, a cosine COSθ1 is found out from two vectors constituted of three vertexes, i.e., a certain vertex (i) and its before and after vertexes and a cosine COSθ2 is found out from one of the vectors and a vector connecting the vertex (i) to a point to be evaluated (steps S2, S3). Then whether the point to be evaluated exists in the area or not is judged from a difference between both the cosines COSθ1 , COSθ2 . (steps S4 to S7).</p> |
