dB Conversion
Hello there, i am a bit confused about dB conversion, i got an equation which consist of two parts say P and C, where P is the Power and C is the constant (it doesn't have any power), which have impact on the power. so if i want to convert to db the whole equation so which one i... 19 May 2010 21:35

using fmincon with matrix as variable in stead of vector
I am using fmincon for estimating 6 different variables stored in 2 * 3 matrix C. These are actually probability values of 3 elements across 2 different classes. (row -> class no, column -> data instance no) I have only linear inequality constraints i.e. sum across each column of C should be 1(the constraint we have f... 24 May 2010 14:34
