<p>You can set the decision variables in Wolfram Alpha. E.g.,</p>

<p>I'm working with a fairly complex equation and I need to carry out constrained optimization of the same. The first order differential equations are very messy to solve by hand and hence I thought to use online calculators. Problem with calculators like wolfram is that I cannot choose the variables with respect to which optimization needs to be done. If I use numbers in place of other variables it would defy the purpose. Are there any calculators available online for the problem I have? I am open to use coding based software like Matlab.</p>
<p>For example:<br />
Maximize <span class="math-container">$\ ax^b−x $</span><br />
w.r.t <span class="math-container">$\ x $</span><br />
s.t. <span class="math-container">$\ x&gt;0,a&gt;1,0&lt;b&lt;1 $</span><br />
The original problem is multivariable and much more complex. I don't want to optimize with specific values for a,b.</p>

For example:

s.t. $\ x>0,a>1,0

You can set the decision variables in Wolfram Alpha. E.g.,

> maximize [{x\*q-q^2+a} , {q}]

maximizes the function $x\*q-q^2+a$ w.r.t. the variable $q$.
  
 For further details read the [reference sheet of the Maximize function](https://reference.wolfram.com/language/ref/Maximize.html).
