Dot indexing is not supported for variables of this type.

Hi,

I am trying to use the SURROGATES Toolbox 3.0 (BETA). developed by Dr. Felipe Viana who has last tested it with MATLAB 7.0. The code is showing the following error when I try to execute the surrogate functions:

Dot indexing is not supported for variables of this type.

Error in srgtsGPEvaluate (line 49)

yhat = gpml_gpr_evaluate(x, srgtSRGT.GP_CovarianceFunction, srgtSRGT.GP_LogTheta, srgtSRGT.P, srgtSRGT.T);

Error in Samplespacefull (line 11)

Yhat = srgtsGPEvaluate(predictor, Po);

I am using version R2019b. Is there a way in which I can continue using this toolbox with minimum modifications to the code?

Thank you in advance.

This is the manual provided with the toolbox

Samplespacefull is my matlab file, predictor is a 3 variable sample matrix and Po is the response variable.

Po must be a structure. It is the first output of srgtsGPFit.

Okay. will try that
