Spline Interpolation of Sine Data Usesplineto interpolate a sine curve over unevenly-spaced sample points. x = [0 1 2.5 3.6 5 7 8.1 10]; y = sin(x); xx = 0:.25:10; yy = spline(x,y,xx); plot(x,y,'o',xx,yy) Spline Interpolation with Specified Endpoint Slopes ...
General Spline Interpolation If you want to interpolate at sites other than the breaks and/or by splines other than cubic splines with simpleknots, then you use thespapicommand. In its simplest form, you would saysp = spapi(k,x,y); in which the first argument,k, specifies theorderof t...
Spline Interpolation of Sine Data Copy Code Copy Command Use spline to interpolate a sine curve over unevenly-spaced sample points. Get x = [0 1 2.5 3.6 5 7 8.1 10]; y = sin(x); xx = 0:.25:10; yy = spline(x,y,xx); plot(x,y,'o',xx,yy) Spline Interpolation with Specifie...
s= spline(x,y,xq)returns a vector of interpolated valuesscorresponding to the query points inxq. The values ofsare determined by cubic spline interpolation ofxandy. s= spline(x,y,xq)返回与xq中的查询点对应的内插值s的向量。 s的值由x和y的三次样条插值确定。 xq是使用MATLAB画模拟信号图时,坐...
MATLAB Online에서 열기 Hi Bhagya, I understand that you want the spline to follow the trajectory of a polygon and pass around the waypoints. The code you provided uses a simple spline interpolation which doesn’t consider the polygon trajectory. To achieve this...
