Open in MATLAB Online I'm trying to make a code that uses Euler's method into a function that can be called later. This is the original, which works as intended. ThemeCopy K = 167; H = 100; Te = 20; w = 0.01; T(
警告信息，在循环中变量segment的维数可能变化，建议预分配空间以提高速度；the function return value "nframe" might be unset.错误信息，函数返回值nframe未被定义 前面两个是警告，不影响程序运行（但警告信息通常也可能是潜在的错误），真正影响程序运行的是第三个。注意在函数体中给返回参数nframe赋...
