    <p>You're looking for <a href="http://www.mathworks.nl/help/matlab/ref/eval.html" rel="nofollow">eval</a>, but that would probably still require a loop (yes you could generate a lengthy command, but do you really want that?):</p> <p>Loop (please do not use this!):</p> <pre><code>for ii=1:numel(parvals) eval([parstrs(ii) '=parvals(' ii ')']); end </code></pre> <p><code>eval</code> is most of the time totally not needed and discouraged; changing to cells is much easier to manage and use. You already have the variables in a vector, what's the problem with just using indexing to inspect them?</p> <p>You should explain your application a bit more, so we can understand what you're really after, <em>why</em> you really want to use this kind of variable assignment.</p> <p>For exporting variables outside from a gui to the base matlab environment, you can switch to <a href="http://www.mathworks.nl/help/matlab/ref/evalin.html" rel="nofollow">evalin</a>, and use it as follows:</p> <pre><code>function main_gui() % do your thing, generate some values parvals = [1 2 3]; % now is the time to export give_me_my_vars({'a','b','c'}); % note that the following function is nested: function give_me_my_vars(parstrs) for ii=1:numel(parvals) evalin('base',[parstrs(ii) '=' parvals(ii)]); end end end </code></pre> <p>This is only possible for simple scalars, which fit in a string. I think you actually want to look for something to switch variables from one workspace to another (gui to base), but I don't know if that'd be possible.</p>

    1. COThe application has to do with curve fitting. I have the right side of an ode which will be called a large number of times and parameters will be estimated. To get an idea of which parameters can be estimated, I want to send in a cell of the parameters names to the rhs function (where the order of variables names coincides with the order of the values in the input vector from the optimizer).

    2. COyeah, I already thought it'd be something like that, check my edit

    3. COI've experimented extensively with eval, evalin, arrayfun, cellfun, etc. eval works, but there still has to be the loop. arrayfun and cellfun get cranky with scope issues when I try to give them anonymous functions which call eval.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
