I am having trouble using complex numbers to find the determinant of a square matrix. This is what I have so far, but my deter function is having trouble. I tried tracing it by hand, but I can't find anything. If someone would help I would really appreciate it. #include <iostream.h> #include <iomanip.h> #include <stdlib.h> const int maxsize=10; struct compl{ double r; double i; }; compl add(compl m, compl n) { compl sum; sum.r=m.r + n.r; sum.i=m.i + n.i; return sum; } compl subtr(compl m, compl n) { compl diff; diff.r=m.r - n.r; diff.i=m.i - n.i; return diff; } compl mult(compl m, compl n) { compl prod; prod.r=(m.r * n.r)-(m.i * n.i); prod.i = (m.r * n.r)+(n.r * n.r); return prod; } compl divide(compl m, compl n) { compl quot; quot.r=(m.r * n.r + m.i * n.i)/(m.r * n.r + n.i * n.r); quot.i=(n.r * m.i - m.r* n.i)/(n.r * n.r + n.i * n.r); return quot; } void matrix(compl source[maxsize][maxsize], compl dest[maxsize][maxsize], int xexclude, int yexclude, int currsize) /* Input: Output: Purpose/Method: */ { int row, //rows c, //columns cr; //current row for (row=0; row<currsize; row++) { if(row<yexclude) {cr=row;} else {cr=row-1;} for (c=0; c<currsize; c++) { if (row!=yexclude&&c!=xexclude) { if(c<xexclude) {dest[cr][c]=source[row][c];} else {dest[cr][c-1]=source[row][c];} } } } } compl deter(compl source[maxsize][maxsize],int currsize) /* Input: User input from main pertaining to matrix size. Output: Determinant returned. Purpose/Method: Recursion */ { compl dest[maxsize][maxsize]; compl total; int yexclude; total.r=0; total.i=0; for(yexclude = 0; yexclude<currsize; yexclude++) { int xexclude = 0; if (currsize==1) { total=source[0][0]; return total; } matrix(source, dest, xexclude, yexclude, currsize); if (yexclude%2==0) { total= add( total, mult(source[0][xexclude], deter(dest, currsize-1))); } else { total= subtr(total, mult(source[0][xexclude], deter(dest, currsize-1))); } } return total; } void main(void) /* Input: User Input of Currsize, which determines matrix size and numbers in columns of matrix. Output: Returned value of deter function. Purpose/Method: Using the 2 dimensional arrays to store the values of the matrix. */ { int cn, //column number currsize, //current size rn, //row number row, //row c; //column cout<<"Enter Matrix size"<<" : "<<'\n'; cin>>currsize; compl source[maxsize][maxsize]; for(rn=0; rn<currsize; rn++) { cout<<"Enter a column: "<<rn<<" : "<<'\n'; for(cn=0; cn<currsize;cn++) { cin>>deter(source, currsize).r >>deter(source, currsize).i; } cout<<"Your Determinant" <<" : " <<deter(source, currsize).r <<"+" <<deter(source, currsize).i <<"i"; } }
