PURPOSE:To simplify the procedure of calculation and the control of a memory space by expressing space vectors by one vector string. CONSTITUTION:In the space vector expression, ID corresponds to row number or column number of a matrix. Factors a1 and a2 indicate that vectors X1 and X2 exist continuously from the a1-th factor and vectors X3-X5 exist continuously from the a2-th factor respectively. All factors having no vector are regarded as ''0''. Said expression makes it possible to express the space vectors by one vector string without using a mask vector. |
