MATLAB ribbon()用法及代码示例

ribbon(Y) // It plots the columns of Y as separate three-dimensional ribbons using
X = 1:size(Y,1).
ribbon(X,Y) // It plots X versus the columns of Y as three-dimensional strips. X and Y are vectors of a similar size or matrices of the same size. X can be the row or a column vector, and Y a matrix with length(X) rows.
ribbon(X,Y,width) // It specifies the width of the ribbons. The default is 0.75.
ribbon(axes_handle,...) // It plots into the axes with handle axes_handle instead of the current axes (gca).
h = ribbon(...) // It returns a vector of handles to surface graphics objects. ribbon returns one handle per strip.
