Linear Algebra and the C Language/a087

__NOTOC__ Balancing a chemical equation a) The system: double ab[RA*(CA+C1)]={ // x1 x2 x3 x4 b +0, +0, -0, -0, 0, //C +0, +0, -0, -0, 0, //H +0, +0, -0, -0, 0, //O }; Each coefficient must have a column. Here four coefficients therefore four columns. Each atom must have a row. Here, three atoms, so three rows. The coefficients on the left side of the chemical equation must have a positive coefficient. (x1, x2) The coefficients on the right side of the chemical equation must have a negative coefficient. (x3, x4) b) The first column: double ab[RA*(CA+C1)]={ // x1 x2 x3 x4 b +1, +0, -0, -0, 0, //C +4, +0, -0, -0, 0, //H +0, +0, -0, -0, 0, //O }; x1 is related to two atoms C and H. There is one C that we write in the first column of the first row. There are four H that we write in the first column of the second row. c) The second column: double ab[RA*(CA+C1)]={ // x1 x2 x3 x4 b +1, +0, -0, -0, 0, //C +4, +0, -0, -0, 0, //H +0, +2, -0, -0, 0, //O }; x2 is related to one atome O. There are two O that we write in the second column of the third row. d) The third and the fourth columns: (With negative coefficients) double ab[RA*(CA+C1)]={ // x1 x2 x3 x4 b 1, 0, -1, -0, 0, //C 4, 0, -0, -2, 0, //H 0, 2, -2, -1, 0, //O }; Now we need to introduce this system into the file: c00a.c.
