matlab - how to convert from type logical to matrice - 


function matb = mbin_init n=6; p=4; sm=1; while(sm>0)     matbin=rand(p,n)>=0.5;     sv = sum(matbin,2)==0;     sm = sum(sv); end matb.matbin = matbin ; end

this function create random binary matrices of size(p,n). have created other search if there colomn of zeros in matrix1 @ position p, if yes matrix2 take column of zeros in same position p.

function [ matb1 ] = replace( ) matbin1 = mbin_init(); matbin2 = mbin_init(); indexcolonnenulle = 0; i=1:4    if sum(matbin1(:,i)) == 0         indexcolonnenulle = i;    end end if(indexcolonnenulle > 0)     matbin2(:,indexcolonnenulle) = 0; end matb1.matbin2 = matbin2; end

an error appear when executing these functions!! undefined function 'sum' input arguments of type 'struct'.

error in replace (line 6) if sum(matbin1(:,i)) == 0

what have please?? thanks

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
