Inverting , or transposing a matrix is one operator. It helps if the supporting hardware understands vectormode. APL allowed very small programs that ran for hours to finish. I don't think that APL programs generated more efficient code on a B7700 than the Algol (Burroughs extended) compiler though.</div> <div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif, sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"><br></div> <div style="font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif, sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);">Verzonden vanaf mijn BlackBerry 10-smartphone.</div> <table width="100%" style="background-color:white;border-spacing:0px;"> <tbody><tr><td colspan="2" style="font-size: initial; text-align: initial; background-color: rgb(255, 255, 255);"> <div style="border-style: solid none none; border-top-color: rgb(181, 196, 223); border-top-width: 1pt; padding: 3pt 0in 0in; font-family: Tahoma, 'BB Alpha Sans', 'Slate Pro'; font-size: 10pt;"> <div><b>Van: </b>Mark Wickens</div><div><b>Verzonden: </b>zaterdag 30 april 2016 08:38</div><div><b>Aan: </b>hecnet@update.uu.se</div><div><b>Beantwoorden: </b>hecnet@Update.UU.SE</div><div><b>Onderwerp: </b>Re: [HECnet] OFF-TOPIC (but it's Friday guys): APL FAIL</div></div></td></tr></tbody></table><div style="border-style: solid none none; border-top-color: rgb(186, 188, 209); border-top-width: 1pt; font-size: initial; text-align: initial; background-color: rgb(255, 255, 255);"></div><br><div id="_originalContent" style="">I have an interest in APL too which I struggle to fully understand.
