如何使此程序正常运行？

h=6:2:18; %一个1*7的double

t=[18,20,22,25,30,28,24;15,19,24,28,34,32,30]; %一个2*7的double

x=6.5:2:17.5; %一个1*6的double

y=interp1(h,t,x,'spline'); %用“3次样条插值求近似值”

错误使用 interp1>reshapeAndSortXandV

LENGTH(X) 和 SIZE(V,1) 必须相同。

出错 interp1 (第 128 行)

[X,V,orig_size_v] = reshapeAndSortXandV(X,V);

As the error states, The function interp1() expects the length of the first input to be equal to the number of rows in the second input.

To achieve that, you can transponse 't' -

h=6:2:18;   %一个1*7的double
t=[18,20,22,25,30,28,24;15,19,24,28,34,32,30];   %一个2*7的double
x=6.5:2:17.5;   %一个1*6的double

%Transposing t
t = transpose(t);
%Interpolation
y=interp1(h,t,x,'spline')

y = 6×2

18.5020 15.6553 20.4986 20.3355 22.5193 24.9089 26.3775 29.6383 30.2051 34.2568 26.8178 30.9594
