MATLAB: alternative to CSAPE function? (Aerospace application) Hi, I need it to spline fit an airfoil. This function is special because it has "end conditions". So the trailing edge will remain intact. I am looking for an alternative because I don't have Spline Toolbox and this is the only function I need. MathWorks Original Function Link: http://www.mathworks.com/access/helpdesk/help/toolbox/splines/index.html?/access/helpdesk/help/toolbox/splines/csape.html&http://www.mathworks.com/cgi-bin/texis/webinator/search/?db=MSS&prox=page&rorder=750&rprox=750&rdfreq=500&rwfreq=500&rlead=250&sufs=0&order=r&is_summary_on=1&ResultCount=10&query=csape&submitButtonName=Search" [Broken] I found this: http://www.mathworks.com/matlabcentral/fileexchange/17610 [Broken] but it doesn't say anything about end conditions. Please let me know of any other (maybe user created) function that can do this. Just a tool, it can be for excel anything else. Thank you.
