Binary Matrix Manipulation
I want to find the first occurrence of 1 in each row of a binary matrix and convert all other elements to 0 AND convert all elements to the right of 1 to one. For example. A = [0 0 0 1; 1 0 0 1; 0 0 0 0; 0 1 0 0]. Then I want two matrices: A1 = [ 0 0 0 1; 1 0 0 0; 0 0 0 0; 0 1 0 0] and A2 = [0 0 0 1; 1 1 1 1; 0 0 0 0... 21 Jul 2010 16:55

Optimization: Setting bounds depending on solution
Hi, I'm using a lsqnonlin-function to solve an optimization problem: ysp = lsqnonlin(@fun4,ysp0,lb,ub,optionslsq); Within fun4 a set of parameters are optimized which are arranged in a vector. lb and ub are the corresponding vectors of the upper and lower bounds. From previous information I know, that cer... 21 Jul 2010 02:41

"Marie " <none(a)nospam.com> wrote in message <i25prc$7cg$1(a)fred.mathworks.com>... Dear Matlab Users, Matlab typically puts a scale factor (i.e. x 10^5) on an axis when the units are too large to display. For example, in Matlab r2008b: plot(linspace(0,100), linspace(0,1e6)) will produce y labels ... 21 Jul 2010 02:41
