写一个用c语言使用7参数转换坐标的代码

好的，我会尽力回答你的问题。

以下是用C语言编写的7参数转换坐标的代码：

#include <stdio.h>
#include <math.h>

#define PI 3.14159265358979323846
#define RAD(a) ((a) / 180.0 * PI)
#define DEG(a) ((a) / PI * 180.0)

void trans_7param(double x, double y, double z, double a, double b, double c, double m, double n, double p, double *xout, double *yout, double *zout)
{
    double r, s, t;
    double phi, omega, kappa;
    double cosphi, sinphi, cosomega, sinomega, coskappa, sinkappa;

    phi = RAD(a);
    omega = RAD(b);
    kappa = RAD(c);

    cosphi = cos(phi);
    sinphi = sin(phi);
    cosomega = cos(omega);
    sinomega = sin(omega);
    coskappa = cos(kappa);
    sinkappa = sin(kappa);

    r = m - cosphi * coskappa * n + cosphi * sinkappa * p;
    s = cosomega * p + sinomega * sinphi * coskappa * n + sinomega * sinphi * sinkappa * p - sinomega * cosphi * m;
    t = sinomega * coskappa * n - sinomega * sinkappa * p + cosomega * m;

    *xout = x + r;
    *yout = y + s;
    *zout = z + t;
}

int main()
{
    double xin, yin, zin;
    double a, b, c;
    double m, n, p;
    double xout, yout, zout;

    /* 举例 */
    xin = 1000.0;
    yin = 2000.0;
    zin = 3000.0;
    a = 45.0;
    b = -30.0;
    c = 60.0;
    m = 100.0;
    n = -200.0;
    p = 300.0;

    trans_7param(xin, yin, zin, a, b, c, m, n, p, &xout, &yout, &zout);

    printf("input: x=%.6lf y=%.6lf z=%.6lf\n", xin, yin, zin);
    printf("7-parameters: a=%.6lf b=%.6lf c=%.6lf m=%.6lf n=%.6lf p=%.6lf\n", a, b, c, m, n, p);
    printf("output: x=%.6lf y=%.6lf z=%.6lf\n", xout, yout, zout);

    return 0;
}
