matlab - Delete Rows from matrix -

-

this question has answer here:

i have vector x (786432*1) , t(786432*1).

i want delete rows x have value 2 , want delete same(corresponding)rows of t -(for example delete x(1,1) , t(1,1)) no important t values. confusing loop (index)

> [r c]=find(x==2);

how find same r , c in vector t?

how implement in matlab? please 1 can help!

you got how find indices remove:

idxs = find(x==2);

you can remove element @ indices with:

x(idxs) = []; t(idxs) = [];

example:

>> x=randi(10,1,7); >> t=randi(10,1,7); >> x  x =      10     3     2     2     1     5     5  >> t  t =       6     9     3     4     2    10     7  >> idxs = find(x==2)  idxs =       3     4  >> x(idxs)=[]  x =      10     3     1     5     5  >> t(idxs)=[]  t =       6     9     2    10     7  >>

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 .
