matlab - index out of bounds error because numel -



matlab - index out of bounds error because numel -

it loops through until lastly time , error "attempted access eq_num(8); index out of bounds because numel(eq_num)=7."

n_node=8 n_pre_disp=2 disp_node= [2 7] eq_num = 0; = 1:n_pre_disp node=disp_node(i); eq_num(node) = -i; end row = 0; = 1:n_node if (eq_num(i)==0) row = row+1; eq_num(i)=row; end end

in loop

eq_num = 0; = 1:n_pre_disp node=disp_node(i); eq_num(node) = -i; end

you create eq_num 7 elements; highest value node takes highest value in disp_node(1:2) 7.

in loop

row = 0; = 1:n_node if (eq_num(i)==0) row = row+1; eq_num(i)=row; end end

you loop on i=1:8 , seek execute eq_num(8)==0.

you need prepare something, don't know what. perchance think matlab arrays indexed 0, they're not, first index matlab array 1.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...

javascript - mongodb won't find my schema method in nested container - i trying access method of schema stored within mixed container. here situation : have cases model can many different things, have schema each of these things stored in "casecontent" mixed property. var caseschema = mongoose.schema({ casecontent : {}, object : {type:string, default : "null"}, collision : {type : boolean, default : false} }); the casecontent property filled model of 1 of schemas, 1 exemple : var treeschema = new mongoose.schema({ applecount : {type : number, default : 3} }); treeschema.methods.dostuff = function (data) { console.log('hey, listen'); homecoming true; }; then, want utilize method of schema original container : caseschema.methods.dostuff = function (data) { if (this.casecontent.dostuff !== undefined) { this.casecontent.dostuff(); console.log('it worked'); } else { ...
