matlab - Make multiple histograms for each column in matrix -

-

i loop through each column in 306x20 matrix, nan values filling in empty spaces, , create histogram each row (finish 20 histograms). best way this? pseudocode implement:

for = 1:(number of columns)      % loop through each column generate different histogram same      % x , y labels , title      % hist(data, 20) end

thank you

i assume want separate figure each histogram. can achieved for-loop , figure-statement open new figure in each iteration. in matlab version r2014b , above, use histogram-function plot histogram, in versions below r2014b use hist instead (hist still works in r2014b , above). both functions ignore nan-values in dataset.

% generate random data nan-values x = randn(306,20); = randi(5,[306,20]); x(a==3) = nan;  % plot histograms = 1:size(x,2)     figure;     histogram(x(:,i)) % before r2014b use "hist" instead     title(['histogram of row ',num2str(i)]);     xlabel('bins');     ylabel('frequency'); end

this gives following result last row: result

python - No exponential form of the z-axis in matplotlib-3D-plots -

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

-
i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
