<p>PURPOSE: To easily solve differential equations over a wide range by providing the device, which makes a differential equation discrete and solves specific simultaneous linear equations represented with vectors, with an input/output means, a control processor, etc., and finding the solution by a specific means. CONSTITUTION: The device which makes the differential equation discrete and solves the simultaneous equations Ax=b (A: matrix showing the coefficients of the simultaneous linear equations, x: vectors showing quantities to be found, b: vectors showing known quantities) represented with the vectors has the input/ output means 1 and 3, the control processor 2, a memory 4, and a product sum arithmetic means 5. The control processor 2 takes a filter coefficient (h) out of the memory, the product sum arithmetic means 5 generates an incomplete discrete wavelet conversion matraix W and its transposed matrix WT and performs conversion into WAWTP=q(x=WTP and q=wb) by using the incomplete discrete wavelet conversion matrix W and transposed matrix WT, and the arithmetic means 5 finds the vectors (p) and (q) to find the vector (x).</p> |
