能否基于该matlab的二维波动方程代码改为C语言的二维波动方程代码

如有帮助请帮忙采纳，谢谢！
可以将该MATLAB代码转换为C语言代码。以下是转换后的C代码：

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

#define M 320
#define N 32
#define K 32
#define T 3.0
#define HX 1.0/(N-1)
#define HY 1.0/(K-1)
#define HT T/(M-1)
#define ALPHA_X HT*HT/(HX*HX)
#define ALPHA_Y HT*HT/(HY*HY)

double u[M][N][K];

void initialize() {
    int i, j, k;
    double x, y;
    for (i = 0; i < M; i++) {
        for (j = 0; j < N; j++) {
            for (k = 0; k < K; k++) {
                u[i][j][k] = 0.0;
            }
        }
    }
    for (j = 0; j < N; j++) {
        for (k = 0; k < K; k++) {
            x = j*HX;
            y = k*HY;
            u[0][j][k] = sin(4*M_PI*x) + cos(4*M_PI*y);
            u[1][j][k] = sin(4*M_PI*x) + cos(4*M_PI*y);
        }
    }
}

void solve() {
    int i, j, k;
    for (i = 1; i < M-1; i++) {
        for (j = 1; j < N-1; j++) {
            for (k = 1; k < K-1; k++) {
                u[i+1][j][k] = 2.0*u[i][j][k] - u[i-1][j][k] + ALPHA_X*(u[i][j+1][k] + u[i][j-1][k] - 2.0*u[i][j][k]) + ALPHA_Y*(u[i][j][k+1] + u[i][j][k-1] - 2.0*u[i][j][k]);
            }
        }
    }
}

int main() {
    int i, j, k, t;
    double x, y;
    initialize();
    solve();
    for (i = 0; i < M; i++) {
        printf("Iteration %d:\n", i);
        for (j = 0; j < N; j++) {
            for (k = 0; k < K; k++) {
                x = j*HX;
                y = k*HY;
                printf("%f %f %f\n", x, y, u[i][j][k]);
            }
        }
    }
    return 0;
}

请注意，此代码仅仅是一种可能的转换方式，可能需要根据具体情况进行调整和优化。此外，由于MATLAB和C语言的语法和语义有所不同，因此在转换时需要进行一些修改和适应。
