From: Eric on 26 Mar 2010 17:24 I'm wondering if anybody else has run into this problem. I have code where I use containers.Map objects to keep track of arrays by their names. This no longer seems to work in Matlab R2010a. For example, the following works fine in R2009b: >> A = containers.Map('hello',[1 2]); >> A = containers.Map('hello',[1 2]); A('hello') ans = 1 2 However, in Matlab R2010a: >> A = containers.Map('hello',[1 2]) ??? Error using ==> containers.Map Specified value type does not match the type expected for this container. According to the manual's Map Containers page: "The values stored in a Map can be of any type. This includes arrays of numeric values, structures, cells, strings, objects, or other Maps." Does anybody know if this is a bug or if the syntax has changed? What is the correct syntax for the line that worked in R2009b? Thanks, Eric
From: Eric on 26 Mar 2010 17:28 My example of the code that works in R2009b should read: >> A = containers.Map('hello',[1 2]); A('hello') ans = 1 2
From: Eric on 26 Mar 2010 17:36 Okay, I'm going to stop playing with this now, but... If I replace [1 2] with [W1 W2] where W1 and W2 are instantiations of a class I've written, the containers.Map works fine. It apparently only fails for arrays of numbers (not objects). Weird. -Eric
From: Bruno Luong on 26 Mar 2010 18:51 Well weird indeed. A workaround may be put the curly brackets around: A = containers.Map({'hello'},{[2 1]}) Bruno

This syntax also works: A = containers.Map('hello',[2 1],'uniformValues', false) Bruno |
