Hi Praveen,
"bspline(t)" plots the B-spline with knot sequence "t", as well as the polynomial pieces of which it is composed.
“bspline(t, window)” plots the B-spline with knot sequence "t", as well as the polynomial pieces of which it is composed, in the subplot specified by "window".
You can refer the following code snippet below for utilizing the "bspline" function:
% first create a knot sequence. A knot sequence must be non-decreasing
x = [0 1.5 2.3 4 5];
% Then plot the B-spline with knot sequence "x", as well as its polynomial pieces, by using the bspline function
bspline(x)
% Create a second knot sequence.
y = [2 3 4 5];
% Plot the B-spline with knot sequence y in the same figure but in a different subplot.
bspline(x,1)
bspline(y,2)
You can refer to the below MathWorks documentation to know more about "bspline" and splines in curve fitting toobox:
Hope this helps!
