用matlab中的拟合函数工具箱cftool中的高斯函数拟合后得到如图结果.
我根据拟合的参数,得出拟合方程后,将X代进去算,结果全为0,这是怎么回事啊,
用matlab拟合函数x=[677.451012953104\x051553.85010683228\x052528.37198845515\x053528.52265096343\x054508.63359601970\x055508.98978734822\x056511.01270638502\x057511.64313623208\x058508.10474633929\x059505.86450990300\x0510509.0428619525\x0511503.
我尝试了一下,没有问题.输出数据和拟合一样.你是不是程序哪里出问题了.
