Unexpected MATLAB expression? (trying to create a function) - 


load('matrix.mat'); userinput = input('input value 1-5') dayreport = sum(matrix(:,end 2);==userinput)

i trying retrieve number of rows in column 2 of loaded matrix corresponds userinput. however, when try run code, says there error in third line (simply, "unexpected matlab expression"). ideas why is?

edit: found solution, turns out don't need "end" or semicolon within sum function. 

load('matrix.mat'); userinput = input('input value 1-5') dayreport = sum(matrix(:,2)==userinput)

remove semi-colon , end statement in last line of code. guess want access second column of matrix, , it's matrix(:,2).

also, suspect copied , pasted code somewhere. that's bad programming practice because copied code may work in situation, if try , bring current context, may different you're doing , can result in errors.

see discussion on programmers stack exchange on why should avoid together: https://softwareengineering.stackexchange.com/questions/87696/is-copy-paste-programming-bad

css - SVG using textPath a symbol not rendering in Firefox -

using textpath within symbol doesn't render in firefox. renders fine in latest chrome , ie, when try reference symbol, svg text doesn't render in firefox (37.0.1) - first box appears empty. code below (no external dependencies), there should 2 boxes word test flowing vertically in centre of each. edit: thought issue somehow involved flexbox layout, until paul pointed out issue exists without flexbox layout. the html is: <div> <svg id="not_working" viewbox="0 0 250 1200" preserveaspectratio="xmidymid meet"> <symbol id="test_symbol1" preserveaspectratio="xmidymid meet" viewbox="0 0 250 1200"> <path id="test_symbol_path" d="m 100 1200 l 100 0" /> <text font-size="100" fill="red"> <textpath text-anchor="middle" startoffset="50%" xlink:href="#test_symbol_path...

datatable - Matlab struct computations -

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
