Hi people I have the error I named the question in the function: (With "here" I comment where the compiler send me the error):
Code:void ftshifting(matriz filter,int rows,int cols){ double r2,c2,tmp1_3,tmp2_4; r2 = (rows+1)/2; c2 = (cols+1)/2; for (int i = 0; i<rows/2; i++){ for (int k = 0; k<cols/2; k++){ tmp1_3 = filter[i][k]; filter[i][k] = filter[i+r2][k+c2]; //error filter[i+r2][k+c2] = tmp1_3; //error tmp2_4 = filter[i+r2][k]; //error filter[i+r2][k] = filter[i][k+c2]; //error filter[i][k+c2] = tmp2_4; //error } } } double **createmat(int rows,int cols){ double **m; m=new double*[rows]; for(int i=0;i<rows;i++) m[i]=new double[cols]; return m; }The strange thing is that it worked before inserting the typedef double**matriz;Code:
I tested the function and it worked. Also, other function use this data and it works normally, example: (no errors at compiler time)
Code:void pre_filter_Computations(matriz radius,matriz theta,int cols,int rows){ double X[rows][cols],Y[rows][cols]; double x[cols],y[rows]; double epsilon = 0.0001; for(int i=0;i<cols;i++){ x[i]=((double)(i-cols)/2)/((double)cols/2); } for(int z=0;z<rows;z++){ y[z]=-(((double)(z-rows)/2)/((double)rows/2)); } for(int m=0;m<cols;m++){ for(int n=0;n<rows;n++){ X[m][n]=x[m]; Y[m][n]=y[n]; } } for(int a=0;a<rows;a++){ for(int b=0;b<cols;b++){ X[a][b] = pow(X[a][b],2); Y[a][b] = pow(Y[a][b],2); X[a][b] = X[a][b] + Y[a][b]; radius[a][b] = sqrt(X[a][b]); } } radius[rows/2][cols/2]=1; for(int a=0;a<rows;a++){ for(int b=0;b<cols;b++){ radius [a][b]= radius[a][b] + epsilon; theta[a][b] = atan2(Y[a][b],X[a][b])*180/PI; } } }
