This worked up to Prime 9, but has no effect in Prime 10 or 11.</P> <P>In Prime 11 a new built-in function "vec" was provided which could be used to turn a range into a vector but also to define a vector right away.</P> <P>So you simply could use</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Werner_E_0-1748629818491.png" style="width: 271px;"><img src="https://www.ptcusercommunity.com/t5/image/serverpage/image-id/123723i5ADC2AA0524625CA/image-dimensions/271x140?v=v2" width="271" height="140" role="button" title="Werner_E_0-1748629818491.png" alt="Werner_E_0-1748629818491.png" /></span></P> <P>&nbsp;</P> Fri, 30 May 2025 18:30:45 GMT https://www.ptcusercommunity.com/t5/Mathcad/Problems-finding-the-maximum-value-of-a-function-within-a-given/m-p/1018176#M217338 Werner_E 2025-05-30T18:30:45Z
