Sometimes there is something matlab continue for loop wrong with the page it’s trying to read which causes the script to stop and display the error. From what I understand you can put the command within a “try” command to continue despite the error like this:try webread(‘www.something that could or could not generate an error.com’) catch continue end First of all; is that the correct way of writing it or would I need to specify anything more after writing “catch”? And can I modify this so that instead of continuing the script it restarts it from the next iteration in the loop? If I write:for i=1:100 try webread(‘www.something that could or could not generate an error.com’) catch end %I want this to cause the loop to jump up to the next value of i and restart the loop end end Matlab won’t understand what I mean with my double end statement. Is there some other way of doing this? I want my script to always ignore errors and just try again with a new iteration. 0 Comments Show all comments Tags errorfor loopwebread Products No products are associated with this question.

Sometimes (randomly) an internet connection problem results (error 111) and matlab stops to execute the m-file algo! Since this files connects to more than 5000 web pages (one per time) it is possible that a connection error is returned in matlab.I simply want the program to resume the operations specified in the m-file.does someone know how to do this?thank you for your help ... 0 Comments Show all comments Tags matlabfinancealgointenretyahoo finance Products No products are associated with this question.

I'm calling this function inside a loop to convert a number of files. There are some cases where my .dat file is corrupted and the function cannot convert and an error occurs, stopping the loop. Now my question is: Is there any command wherein when the error occurs it should skip the current (i) matlab loop continue value in the loop and go for the next increment value (in my case the next file)? matlab loops share|improve this question edited Sep 13 '10 at 15:16 gnovice 88.3k9195283 asked Sep 13 '10 at 15:07 user446468 66113 add a comment| 1 Answer 1 active oldest votes up vote 20 down vote You can do this using a TRY/CATCH statement along with CONTINUE. Place the following inside your loop: try %# Attempt to perform some computation %# The operation you are trying to perform goes here catch exception %# Catch the exception continue %# Pass control to the next loop iteration end EDIT: Amro suggests a good idea in his comment below. You may want to issue a warning showing that the error occurred and for which file, or perhaps you may even want to save a list of the files that failed to convert properly. To do the latter, you can first initialize an empty cell array before you start your loop: failedFiles = {}; %# To store a list of the files that failed to convert Then, after you catch the exception but before you issue the continue command, add the name/path of the current file being converted to the list: ... catch exception failedFiles = [failedFiles; {'currentFi

For each value in these vectors I would like to solve the equation C^x = A^x + B^x. Unfortunately this is an equation that I have found to be solvable only iteratively, so I am attempting to use MATLAB's "solve" function to find a solution for each case. My code is as follows: exponents = zeros(100,1); syms x A = rand(100,1); B = rand(100,1); C = rand(100,1); for i = 1:100 exponents(i) = eval(solve(C(i)^x == A(i)^x + B(i)^x)); end Sometimes, however, the solution is unobtainable, which leads to the error message, "Warning: Explicit solution could not be found." I am okay with this, but if I run into an unsolvable equation, I would like to simply leave the "exponents(i)" unchanged for that iteration and move onto the next one, instead of having my code abruptly stop. Any suggestions? matlab solver share|improve this question edited Dec 7 '12 at 16:00 HebeleHododo 2,7161334 asked Dec 7 '12 at 14:47 Rick C 285 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote accepted If you put the statement that causes the occasional error inside a try/catch statement, then the error will not cause execution to stop. For example, you could try: for i = 1:100 try exponents(i) = eval(solve(C(i)^x == A(i)^x + B(i)^x)); catch exponents(i) = NaN; end; end share|improve this answer answered Dec 7 '12 at 17:51 jerad 1,6881015 Yes, but the problem is s/he's receiving a warning, not an error. –HebeleHododo Dec 7 '12 at 20:54 That was actually a mistake on my part - I didn't know there was a nomenclature difference between "warning" and "error". This solved my problem perfectly. Thank you! –Rick C Dec 7 '12 at 21:21 add a comment| up vote 0 down vote There is not a direct way in MATLAB for catching warnings (at least a documented way). It is not elegant in the slightest, if not downright ugly, you can try polling the output of lastwarn. ... exponents(i) = eval(solve(C(i)^x == A(i)^x + B(i)^x)); [~, ms
