MATLAB - re-arrange matrix by vertically concatenating submatrices -


i having trouble following task: suppose 3x6 matrix:

a =

0.2787    0.2948    0.4635    0.8388    0.0627    0.0435 0.6917    0.1185    0.3660    0.1867    0.2383    0.7577 0.6179    0.7425    0.0448    0.4009    0.9377    0.4821

what divide matrix blocks, this:

a =

0.2787    0.2948  |  0.4635    0.8388  |  0.0627    0.0435 0.6917    0.1185  |  0.3660    0.1867  |  0.2383    0.7577 0.6179    0.7425  |  0.0448    0.4009  |  0.9377    0.4821

and vertically concatenate these blocks final result:

0.2787    0.2948  0.6917    0.1185   0.6179    0.7425   0.4635    0.8388 0.3660    0.1867 0.0448    0.4009 0.0627    0.0435 0.2383    0.7577 0.9377    0.4821

i think if can this, can perhaps arbitrary matrices a. can solve above problem using for-loops, looking vectorised solution.

thanks in advance! n.

consider following:

a = rand(3,6); blksz = 2;  c = mat2cell(a, size(a,1), blksz*ones(1,size(a,2)/blksz)); c = cat(1,c{:})

this assumes size(a,2) evenly divisible blksz

jquery - Invalid Assignment Left-Hand Side -

i trying assign class tag via jquery, resulting in error through firebug says "invalid assignment left-hand side" on fourth line below. <cfoutput> $('.pngfix a').each(function(index) { var hreflink = $(this).attr("href"); if (hreflink.tolowercase() = '../audio.cfm') { $(this).addclass('audioimg'); } }); </cfoutput> looking around online, looks syntax problem, don't seem see it... any tips? thanks if (hreflink.tolowercase() = '../audio.cfm') that attempts assign value, rather check equality. change = operator == .

gmail - Is there any documentation for read-only access to the Google Contacts API? -

i want read-only access user's google contacts. there stackoverflow member wanted this, , received following answer : yes, there is, use https://www.googleapis.com/auth/contacts.readonly scope , "view contacts". this exchange reference read-only access google contacts can find using google. simply using access token obtained attempt read usual google contacts api (i.e. https://www.google.com/m8/feeds ) fails insufficient permissions. similarly, using google contacts api on new target fails 404 errors (for example https://www.googleapis.com/auth/contacts.readonly/default/full ). is there documentation anywhere on how use api, or permissible way access google contacts api full read-write access?
