newrbe matlab2007b vs 2010a

Hi,

Does anyone know if there is a difference in the newrbe function in matlab 2007b and matlab 2010a. The newrbe function I am using works in 2007b but generates an error in 2010a.

    ??? Undefined function or method 'newrbe' for input arguments of type 'double'.  

Error in ==> RBNNtest2 at 87
scene_RBNN=newrbe(target_array,[1],spread_const);

The spread constant is the last item I entered before the scene_RBNN is executed. I have tried entering 1, 1.0 even 0.5 and it still keeps on generating the same error.I tried to access the 2007b documentation but you cannot get it unless you have 2007b activation and I do not have access to it at time.

Any help would be appreciated.

Thanks

newrbe() does exist in R2010a and is documented at http://www.mathworks.com/help/releases/R2010a/toolbox/nnet/newrbe.html

The function is the same as in R2007a, which is documented at http://www.mathworks.com/help/releases/R2007b/toolbox/nnet/index.html?/help/releases/R2007b/toolbox/nnet/newrbe.html

(You should not need at R2007b activation to see R2007b -- but you do need some activation against your community profile.)

The datatype of the parameter has not changed at all. If newrbe is reported to not exist for inputs of type double, then either you do not have the Neural Network Toolbox installed or else it is not licensed (or the install is corrupt.)

I will try a different pc tomorrow and report back. Thanks for the info.

So I tried another computer and the code sure does run without a glitch on 2010a. Gonna reinstall the neural network toolbox on the laptop.

Thanks for pointing me to the right direction..

The call to newrbe should be of the form

scene_RBNN = newrbe(input_array,target_array,spread_const);

Hope this helps.

I guess what I want to know is if there a syntax difference between the two versions or any modifications were made on the 2010.

Thanks

No, the documentation pages are the same between the two versions, except for changes in formatting.
