How to update multiple graphs from one plot in one statement in Matlab? -

-

i have this:

p = plot([0 1], [0 1], [1 2], [1 2]);

i want take each pair , append number.

x = get(p, 'xdata'); y = get(p, 'ydata');  x1 = mat2cell([x{1} double(2)]); y1 = mat2cell([y{1} double(2)]);  x2 = mat2cell([x{2} double(3)]); y2 = mat2cell([y{2} double(3)]);  set(p, 'xdata', [x1; x2], 'ydata', [y1; y2]); % not work  drawnow;

'get' giving me data in format , 'set'-ing in same format data 1 more value each pair.

the error is: conversion double cell not possible.

there number of different ways fetch current plot points , add them. first 2 lines of eitan's answer (using cellfun) 1 way. here's 1 using cell2mat , num2cell:

newx = [2 3];  % new x values add newy = [2 3];  % new y values add x = num2cell([cell2mat(get(p,'xdata')) newx(:)], 2); y = num2cell([cell2mat(get(p,'ydata')) newy(:)], 2);

the key issue note when using set function on multiple handles stated in excerpt documentation:

set(h,pn,mxn_pv) sets n property values on each of m graphics objects, m = length(h) , n equal number of property names contained in cell array pn. allows set given group of properties different values on each object.

as result, single call set has this:

set(p, {'xdata'}, x, {'ydata'}, y);

note length(p) equal 2, property strings placed in cell arrays, , x , y each 2-by-1 cell arrays.

java - activate/deactivate sonar maven plugin by profile? -

i use sonar plugin executes if activated in maven profile. sonar runs on every compile. the problem build fail other team members not have sonar application installed locally. pom.xml checked in team members same copy including sonar configuration, don't want them modify purpose of disabling sonar (they might inadvertently check modified copy in). please advise how configure maven (.m2/settings.xml) and/or pom.xml sonar feature can enabled/disabled local profile. here sonar configuration in each project's pom.xml: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>sonar-maven-plugin</artifactid> <version>1.0</version> <executions> <execution> <id>make-sonar</id> <phase>compile</phase> <goals> <goal>sonar</goal> </goals> </execution> </executions> ...

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...

java - What is the difference between String. and String.this. ? -

this question has answer here: meaning of .this , .class in java 2 answers i'll straight point. im still learning bit of syntax , want know difference between code is code a: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.valueof(i))); } } please ignore fact i undeclared, not lost. code b: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.this.charat(i))); } } what don't yet understand difference in typing string.this , string. i under assumption when use dot operator on class accessing it's static methods(and/or variables if they're not hidden). i have studied little bit , have concluded when using string. accessing string static methods.. when using string.this. i'm accessing methods class buttonz extendi...
