I’m currently investigating this issue on Windows. Here’s what I found: Most Swing Look & Feels don’t support high DPI at all, not even Nimbus even though it’s supposed to be scalable. I found some old blog posts saying that Nimbus might eventually offer high DPI scaling, but apparently that never happened. The one exception … Read more
First you must create an empty figure with the following command. figure(‘name’,’Title of the window here’); By doing this, the newly created figure becomes you active figure. Immediately after calling a plot() command, it will print your plotting onto this figure. So your window will have a title. This is the code you must use: … Read more
I had a similar requirement on my system and this was my solution: In MATLAB there is a function called perl.m, which allows you to call perl scripts from MATLAB. Depending on which version you are using it will be located somewhere like C:\Program Files\MATLAB\R2008a\toolbox\matlab\general\perl.m Create a copy called python.m, a quick search and replace … Read more
You have to use curly braces ({}) to access fields, since the fieldnames function returns a cell array of strings: for i = 1:numel(fields) teststruct.(fields{i}) end Using parentheses to access data in your cell array will just return another cell array, which is displayed differently from a character array: >> fields(1) % Get the first … Read more
x(end+1) = newElem is a bit more robust. x = [x newElem] will only work if x is a row-vector, if it is a column vector x = [x; newElem] should be used. x(end+1) = newElem, however, works for both row- and column-vectors. In general though, growing vectors should be avoided. If you do this … Read more
Jonas’s answer is good, but I had to modify it slightly to get every piece of text on the screen to change: set(gca,’FontSize’,30,’fontWeight’,’bold’) set(findall(gcf,’type’,’text’),’FontSize’,30,’fontWeight’,’bold’)
Just call plt.show() at the end: import numpy as np import matplotlib.pyplot as plt plt.axis([0,50,60,80]) for i in np.arange(1,5): z = 68 + 4 * np.random.randn(50) zm = np.cumsum(z) / range(1,len(z)+1) plt.plot(zm) n = np.arange(1,51) su = 68 + 4 / np.sqrt(n) sl = 68 – 4 / np.sqrt(n) plt.plot(n,su,n,sl) plt.show()
You can concatenate strings using strcat. If you plan on concatenating numbers as strings, you must first use num2str to convert the numbers to strings. Also, strings can’t be stored in a vector or matrix, so f must be defined as a cell array, and must be indexed using { and } (instead of normal … Read more
That’s bug no 961964 of MATLAB known since R2012b (8.0). MATLAB dynamically loads some libs with static TLS (thread local storage, e.g. see gcc compiler flag -ftls-model). Loading too many such libs => no space left. Until now mathwork’s only workaround is to load the important(!) libs first by using them early (they suggest to … Read more
As of release R2016b, you can have local functions in scripts, like so: data = 1:10; % A vector of data squaredData = f(data); % Invoke the local function function y = f(x) y = x.^2; end Prior to release R2016b, the only type of function that could be defined inside a MATLAB script was … Read more
