I have a matrix lets say: <pre class="prettyprint"><code>a = 401.4800 344.0900 305.0300 462.2100 310.0600 397.3400 502.5900 547.7100 429.9600 540.3400 737.3600 491.4700 474.7400 735.8700 </code></pre> I want to get the first and last columns only so that: <pre class="prettyprint"><code>b = 401.4800 502.5900 547.7100 735.8700 </code></pre>

<pre class="prettyprint"><code>b = a(:,[1,end]) </code></pre> This means: all rows (<code>:</code>), first and last column (<code>[1,end]</code>).

how to get first and last column of a matrix in MATLAB?

I have a matrix lets say:

a =
    401.4800  344.0900  305.0300  462.2100  310.0600  397.3400  502.5900
    547.7100  429.9600  540.3400  737.3600  491.4700  474.7400  735.8700

I want to get the first and last columns only so that:

b = 
    401.4800  502.5900
    547.7100  735.8700

b = a(:,[1,end])

This means: all rows (:), first and last column ([1,end]).
