Is a newer version of Matlab always faster? 12 20 (10/12/2012 2:36:08 PM) comp.soft-sys.matlab Hi all, This is a non-technical and generic question about the speed at which different versions of Matlab run. I'm running the same code in two different versions of Matlab on two different computers; o... Jason

eval(sprintf(' ')) not defined for struct input? 2 17 (10/3/2012 11:08:08 AM) comp.soft-sys.matlab Hi all, I have 5 struct arrays, named Sam, Lorry, John, Tim, and Sean. Each has two fields, textdata and data, the first of which is a cell array of strings (1-by-100) and the second is a matrix (1000x100)... Jason

Reading in files with strings of varying size 4 22 (10/2/2012 5:04:07 PM) comp.soft-sys.matlab Hi, I've tried to read tab-delimited data with two rows of header. For example: RandData.txt => A B C D E a b c d e 0 117 64 43 46 0 0 19 33 37 2 191 51 DIV 93 0 19 3 23 21 0 177 0 52 3 0 0 19 87 ... Jason

indexing the left-hand side of the eval expression 2 19 (10/2/2012 8:17:08 AM) comp.soft-sys.matlab Hi, I have an array of structures A, B,..., to Z, each of which has a cell of strings called 'textdata' like A.textdata, B.textdata, C.textdata,..., Z.textdata. In the first cell of each textdata, however,... Jason

making sound 1 38 (12/15/2011 2:03:08 PM) comp.soft-sys.matlab Hi, It may sound like I'm joking, but really, is there a function (or a code already written by someone out there) that keeps making some sound upon the completion of a code? And once I press, say Enter, it s... Jason

Comparing two arrays and taking the common part 1 39 (11/22/2011 6:47:08 PM) comp.soft-sys.matlab Hi all, I have two date series (cell arrays) with different lengths in yyyy/mm/dd format, say D1 and D2, and I'd like to take only the common part without running a for loop. Is there any simple way to implem... Jason

MaxIter vs. MaxFunEval 1 30 (11/14/2011 1:30:32 AM) comp.soft-sys.matlab Hi all, This may be too trivial to ask, but I don't know what the difference between MaxIter and MaxFunEval is, upon using an optimization routine (say, fminsearch or patternsearch). For example, if my objecti... Jason

Warning: Concatenation involves an empty array with an incorrect number of columns 2 29 (11/13/2011 10:40:29 PM) comp.soft-sys.matlab Hi all, I'm getting the following message upon executing my code: Warning: Concatenation involves an empty array with an incorrect number of columns. This may not be allowed in a future release. What the cod... Jason

inconsistent date format 4 33 (11/11/2011 9:53:16 AM) comp.soft-sys.matlab Hi all, My data has very inconsistent formats on dates (strings), which I want to convert to numbers, using datenum. The following is what it looks like: 29/12/04 30/12/04 31/12/04 10/01/2004 10/04/2004 .... ... Jason

zero boundary values for optimization problems? 5 45 (11/1/2011 6:21:28 AM) comp.soft-sys.matlab Hi all, I have a function that takes on 9 parameters, which are found executable using all of patternsearch, ga, and sa. I'm ruling out local optimization solvers here since my function potentially have lots ... Jason

Mex/M file calling precedence 6 173 (11/17/2010 12:08:04 AM) comp.soft-sys.matlab If I have two functions with the same name in the same directory, one of which is an M file and the other a Mex file, which is called by default from Matlab? For example, if I have "foo.m" and "foo.mexw64", wh... Jeff

input arguments of type 'double'. 3 434 (12/15/2010 8:52:05 PM) comp.soft-sys.matlab I am not the most familiar with Matlab, but have been reading through manuals and searching online and can't solve this problem. I have a simple autoregressive and moving average models for interest rate pr... Robert

CSV file importing 4 29 (10/25/2011 8:24:14 AM) comp.soft-sys.matlab Hi all, I have many CSV files that Matlab seems to be struggling importing. Each of them looks like it's comma-separated, but using =importdata(filename,',') it ends up having all characters in each cell, whic... loooooo (29)
