>> doc newrbe
Radial Basis Neural Networks
newrbe
Syntax
net = newrbe(P,T,spread)
2、GRNN (广义回归神经网络)
PNN（概率神经网络）
竞争层
重点函数解读：
• newrbe
– Design exact radial basis network
– net = newrbe(P,T,spread)
• newgrnn
– Design generalized regression neural network
– net = newgrnn(P,T,spread)
• newpnn
– Design probabilistic neural network
– net = newpnn(P,T,spread)
• cputime
– Elapsed CPU time
• round(ceil、fix、floor)
– Round to nearest integer
– Y = round(X)
• length(size)
– Length of vector
– n = length(X)
• find
– Find indices and values of nonzero elements
– [row,col] = find(X, ...)
• .* ./ .\ .^ …… vs * / \ ^ ……
– Multiplication (.*) right division (./) left division (.\) power (.^)
– matrix multiplication (*) matrix right division (/) matrix left division (\) matrix power (^)
