Inplace element-wise operations in rtables
http://www.mapleprimes.com/questions/220764-Inplace-Elementwise-Operations-In-Rtables?ref=Feed:MaplePrimes:Tagged With function
<p>The map[inplace] operation can apply a function to the elements of an rtable, replacing these elements with the result. Using map[inplace,evalhf] can be numerically quite efficient but I would like something more general. For example</p>
<pre class="prettyprint">
x += x +~ v*~dt</pre>
<p>where += in some other languages denotes an inplace addition operation and x and v are Vectors (rtable). Is there a way to do this in Maple?</p>

<p>I didn't even know the erf function existed until doing this problem. I looked up how to use it, so I tried plugging in the explicity form into Maple, hoping it'd solve it, but it just spit back out the erf function.</p>

<p>I am trying to get a number answer. A decimal. Because this is calculating a probability. How do I get Maple to give me a number here? Thanks!</p>

<p>Hello, How to do simple analyse on function? like find intervas where function negative and positive, monotone, critical points... </p>
<p> </p>
<p>And also how to plot them on one graph?</p>
<p>thanks :)</p>

<p>how to find roots of equation J0(xR) = 0 ,R is constant, using maple? I know command for zeros of Bessel function i.e J0(x) = 0. but what to do with different argument?</p>

<pre class="prettyprint">
<span style="font-size:10px;">ha := (diff(c(t), t))/(c(t)*(diff(c(t), t))-c(t));
solve(subs(m=ha,f(m))*subs(m=subs(c(t)=a(t),ha)), f(m)) = subs(m=ha+subs(c(t)=a(t),ha), f(m), f);</span></pre>
<p>just expect to find a function ?<br>
