    <p>As <a href="https://stackoverflow.com/questions/2204579/getting-variable-values-into-a-text-string-matlab/2204594#2204594">Peter</a> and <a href="https://stackoverflow.com/questions/2204579/getting-variable-values-into-a-text-string-matlab/2204631#2204631">Amro</a> illustrate, you have to convert numeric values to formatted strings first in order to display them or concatenate them with other character strings. You can do this using the functions <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/fprintf.html" rel="nofollow noreferrer">FPRINTF</a>, <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/sprintf.html" rel="nofollow noreferrer">SPRINTF</a>, <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/num2str.html" rel="nofollow noreferrer">NUM2STR</a>, and <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/int2str.html" rel="nofollow noreferrer">INT2STR</a>.</p> <hr> <p>With respect to getting <code>ans = 3</code> as an output, it is probably because you are not assigning the output from <code>answer</code> to a variable. If you want to get all of the output values, you will have to call <code>answer</code> in the following way:</p> <pre><code>[out1,out2,out3] = answer(1,2); </code></pre> <p>This will place the value <code>d</code> in <code>out1</code>, the value <code>e</code> in <code>out2</code>, and the value <code>f</code> in <code>out3</code>. When you do the following:</p> <pre><code>answer(1,2) </code></pre> <p>MATLAB will automatically assign the first output <code>d</code> (which has the value 3 in this case) to the default workspace variable <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/ans.html" rel="nofollow noreferrer"><code>ans</code></a>.</p> <hr> <p>With respect to suggesting a good resource for learning MATLAB, you shouldn't underestimate the value of the MATLAB documentation. I've learned most of what I know on my own using it. You can access it <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/learn_matlab/bqr_2pl.html" rel="nofollow noreferrer">online</a>, or within your copy of MATLAB using the functions <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/doc.html" rel="nofollow noreferrer">DOC</a>, <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/help.html" rel="nofollow noreferrer">HELP</a>, or <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/helpwin.html" rel="nofollow noreferrer">HELPWIN</a>.</p>

    1. COThanks, this is very useful. Just one more quick question - if I create an output variable in one function - for example: function a=simple(x); a=x^2; how can i access the value of 'a' from other functions? For example: function b=simple2(x); b=a*x; %calling on a from 'simple'

    2. CO@jefflovejapan: In such a case, your second function would be `function b = simple2(x) b = simple(x)*x;`. In other words, you would call `simple` within `simple2` and its output will be used in the equation for `b`.

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.
