MATLAB Code not working. Trying to store input into an array -

-

i wrote 2 functions, first 1 encrypt

prompt = 'enter sentence encrypt'; dlg_title = 'input'; num_lines = 5; defaultans = {'hello'}; answer = inputdlg(prompt,dlg_title,num_lines,defaultans);  answer = answer{1};     % find out how big square matrix data should = 1:length(answer) % should never run far anyway    if (i^2) > length(answer)         break;    end end  mat_len = i;   % predefine square matrix of numbers forcing matrixa number type matrixa = zeros(mat_len,mat_len);   % iterate through square matrix assigning answer values positions = 1:mat_len     j = 1:mat_len         if (((i-1)*mat_len)+j) <= length(answer)          matrixa(i,j) = answer(((i-1)*mat_len)+j);         else             break;         end     end end matrixa(1)=matrixa(1)*10 matrixa'

this stores ascii code array matrixa , simple matrix operations hide message. instance hello be

   720   108     0    101   111     0    108     0     0

the second function problem is, spossed take input of matrix , convert message. 720 turns 72 h. function instead reads matrixa stored.

prompt = 'enter code decrypt'; dlg_title = 'input'; num_lines = 5; defaultans = {''}; answer = inputdlg(prompt,dlg_title,num_lines,defaultans);  answer = answer{1};    = 1:length(answer) % should never run far anyway    if (i^2) > length(answer)         break;    end end  mat_len = i;   % predefine square matrix of numbers forcing matrixa number type matrixa = zeros(mat_len,mat_len);   % iterate through square matrix assigning answer values positions = 1:mat_len     j = 1:mat_len         if (((i-1)*mat_len)+j) <= length(answer)          matrixa(i,j) = answer(((i-1)*mat_len)+j);         else             break;         end     end end      matrixa'' matrixa(1)=matrixa(1)/10 m2=matrixa.'; result=char(m2(:)).';  result

this code not work. how can read matrix of numbers , convert them characters.

sql - Postgresql tables exists, but getting "relation does not exist" when querying -

i have postgresql db number of tables. if query: select column_name information_schema.columns table_name="my_table"; i list of columns returned properly. however, when query: select * "my_table"; i error: (programmingerror) relation "my_table" not exist 'select *\n "my_table"\n' {} any thoughts on why can columns, can't query table? goal able query table. you have include schema if isnt public one select * <schema>."my_table" or can change default schema show search_path; set search_path my_schema; check table schema here select * information_schema.columns for example if table on default schema public both works ok select * parroquias_region select * public.parroquias_region but sectors need specify schema select * map_update.sectores_point

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
