Re: [Scilab-users] mlist parameters to a function call
that's not the solution to my problem: the last two function calls in which i use xa(1x11) as first argument and three parameters (a1.a2,a3 or d.aa(1,:)) ! here i get an 11x1 result with the wrong(?) three parameters Ed. -- View this message in context: http://mailinglists.scilab.org/mlist-parameters-to-a-function-call-tp4033316p4033318.html Sent from the Scilab users - Mailing Lists Archives mailing list archive at Nabble.com. ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users

If you want to perform a element-wise division, the syntax is t = x(1) - x(2) ./ (T+x(3)) // with ./ instead of / Regards Samuel Gougeon ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users

[Scilab-users] extracting elements of a matrix
Let X be a m×n matrix and f(i) is a column index for the ith row. I want to get a m×1 vector y where y(i)=X(i,f(i)) for 1<=i<=m.

Hello, You will find the Matlab code for the "trandn" function there : http://www.mathworks.com/matlabcentral/fileexchange/53180-truncated-normal-generator/content/trandn.m hth S.

Thanks, works fine now. Seen it in one of the manuals, but didnt realize it applies to functions as well!
