I am using the TreeBagger command to produce the random forest regression model. My syntax is like the following:
My Training_Input data is a matrix of 6768X400 and my Training_Output is a matrix of 6768X998
But while trying to execute I am getting the following error:
Error using classreg.learning.regr.FullRegressionModel.prepareData (line 245)
Invalid data type. Response must be a double or single vector.
Error in TreeBagger/init (line 1346)
Error in TreeBagger (line 616)
bagger = init(bagger,X,Y,makeArgs{:});
Error in Neural_network_OPF (line 71)
I have checked the line inside the FullRegressionModel.m where the error is stemming from, it resulted from a check whether my response variable is vector or float.
I am really confused why this error is popping up. Can anyone help me fix it?

The Training_Output variable has to be a vector of size 6768X1 instead of a matrix.

The sizes of the input function and output target must be
[ I N ] = size(input)
[ O N ] = size (target)
Hope this helps,
