Body
Using the function <a href="https://www.mathworks.com/help/matlab/ref/sub2ind.html" rel="nofollow noreferrer"><code>sub2ind</code></a> to create a <a href="http://www.mathworks.com/help/matlab/math/matrix-indexing.html#f1-85511" rel="nofollow noreferrer">linear index</a> is the typical solution to this problem, as shown in this <a href="https://stackoverflow.com/q/792683/52738">closely-related question</a>. You could also <a href="https://stackoverflow.com/q/1146719/52738">compute a linear index yourself</a> instead of calling <code>sub2ind</code>. However, your case may be simpler than those in the other questions I linked to. If you're only ever indexing a single point with your <code>current_point</code> vector (i.e. it's just an n-element vector of subscripts into your n-dimensional matrix), then you can use a simple solution where you convert <code>current_point</code> to a cell array of subscripts using the function <a href="https://www.mathworks.com/help/matlab/ref/num2cell.html" rel="nofollow noreferrer"><code>num2cell</code></a> and use it to create a <a href="https://www.mathworks.com/help/matlab/matlab_prog/comma-separated-lists.html" rel="nofollow noreferrer">comma-separated list</a> of indices. For example: <pre><code>current_point = [1 2 3 ...]; % A 1-by-n array of subscripts subCell = num2cell(current_point); % A 1-by-n cell array of subscripts output_matrix(subCell{:}) = val; % Update the matrix point </code></pre> The operation <code>subCell{:}</code> creates the equivalent of typing <code>subCell{1}, subCell{2}, ...</code>, which is the equivalent of typing <code>current_point(1), current_point(2), ...</code>.

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.
