Response surface modeling

Two functions are provided to read and use the Response Surface Model files generated by the Design Exploration tool:

• the amersmreadrsm function reads an RSM file, selects one particular response and returns it as a matrix or vector, depending on the order of the RSM,

• the amersmcreatevec function helps to evaluate the RSM at a specified point, by creating the vector of all the values of the variables raised to the power up to the required order.

A first or second order RSM is represented by the matrix of the corresponding quadratic form, whereas a third or higher order RSM is represented by a vector of polynomial coefficients. See the manual chapter on the Design Exploration tool for more details.

We will create a simple RSM of one input variable and one output variable to illustrate the use of these functions.
