MATLAB曲线拟合函数的问题!
我需要拟合的数据是这样的:
t1={{1,25755},{2,28500},{3,28197},{4,27239},{5,28924},{6,28317},{7,28367},{8,28317},{9,26745},{10,27404},{11,27710},{12,28882},{13,26853},{14,27205},{15,27145},{16,27588},{17,27758},{18,28065},{19,27872},{20,27804},{21,26063},{22,25851},{23,27469},{24,25273},{25,28002},{26,27084},{27,27494},{28,27443},{29,27365},{30,27616},{31,28382}};
请问需要怎么拟合,
