Database connection expires 3 35 (1/28/2010 9:30:20 PM) comp.soft-sys.matlab Here is something that is a minor frustration. Using the Database Toolbox, I connect to the database just fine. However, after a period of time, that connection seems to expire. (Doesn't seem to be a fixed p... the

Adding RAM will solve Out of Memory? 4 27 (7/26/2006 3:20:37 PM) comp.soft-sys.matlab I know that the dreaded "Out of Memory" error strikes, in general, because of the amount of addressable space available on a 32-bit architecture. I would expect, therefore, that if I have a 1-GB RAM processor,... the

Breakpoint alley disappeared 2 38 (6/4/2006 2:14:41 PM) comp.soft-sys.matlab In the Matlab editor, the breakpoint alley (the column where you set breakpoints) has disappeared. I have NO idea why. How can I get it back. I prefer a solution that does not entail restarting Matlab, but I w... the

Scoring coefficients 0 44 (4/7/2006 7:10:24 PM) comp.soft-sys.matlab I believe the scoring coefficients are k1 = 1/100 k2 = 1/1000 k3 = 1/8 ... the

Filling an array with 3 42 (3/31/2006 1:53:35 PM) comp.soft-sys.matlab Suppose I have a vector v = [4 3 5 1] and from that vector I want to create the array A = [1 1 1 1 0; 1 1 1 0 0; 1 1 1 1 1; 1 0 0 0 0] where the elements of "v" determine the number of ones to put in e... the

Matlab and Visual Source Safe 1 47 (3/21/2006 4:57:25 PM) comp.soft-sys.matlab Suppose I run a function "myFunc.m" from the command window. Then, I use Visual Source Safe to get an updated version of that file. When I run myFunc again, will Matlab automatically use the updated version, or... the

Vector index into vector 0 37 (3/10/2006 5:24:53 AM) comp.soft-sys.matlab In general, if A is an array, and V is a vector used to index into A (via linear indexing), then the shape of A(V) is equal to the shape of V itself. However, if A is a row vector, then A(V) will be a row vect... the

Convert numeric array to cell array of strings 3 81 (2/22/2006 2:19:37 PM) comp.soft-sys.matlab Suppose I have a 4x4 numeric array of integers: >> A = magic(4); From A, I would like to create a 4x4 cell array B, in which each element is B{i,j} = num2str(A(i,j)). It is easy to do this with loops: >> fo... the

Product of distributions --> gaussian 1 36 (1/31/2006 3:23:15 PM) comp.soft-sys.matlab Is there a distribution p(x) such that if x1 and x2 are drawn independently from that distribution, that the distribution of the product x1*x2 is gaussian distributed? ... the

Breakpoints cleared during execution 2 40 (1/26/2006 3:01:40 PM) comp.soft-sys.matlab Are there any operations that will cause breakpoints to be cleared during execution of a series of M-files? I know that the "pack" command will clear breakpoints if done from the command window, but not if it i... the
