I have 7 random variables with their distribution functions. I linked the MATLAB and Opensees program to generate a random variable in MATLAB and get the structure response in Opensees. To obtain an explicit function between the variables and the structure response, using the cftool in MATLAB, only two variables can be entered.
while I have 7 random variables.Now, who can help me to get a Polynomial function by using the response surface method to perform Monte Carlo analysis.
define polynomial function separately ,
once you have add the functionality and its easy to find out
@ Adnan Majeed
In Matlab help, there is following code that expressed for two variable x ,y and output z
how can i define polynomial function for 4 input variable and 1 output?
load franke sf = fit([x, y],z,'poly23')
