C# byte[] to List<byte[]> -

-

i'm trying byte[] array 'a' list 'b', it's not working. have byte array 'a'. 

12344 23425 34426 34533

i 4 item (# of rows) list , isn't working. (setting intermediate byte[] adding it)

    byte[] = {1,2,3,4,4,2,3,4,2,5,3,4,4,2,6,3,4,5,3,3};     list<byte[]> b = new list<byte[]>();     byte[] inter_byte= new byte[5];      (int u=0; u<4; u++)     {          (int p=0; p<5; p++)          {                     inter_byte[u] = file[(5*u) + p];          }          b.add(inter_byte);     }

what i'm getting list 4 rows long, last row. what's best way this?

your byte array reference type, means changing in each loop changes data stored. declaring inside of each loop should work:

 byte[] = {1,2,3,4,4,2,3,4,2,5,3,4,4,2,6,3,4,5,3,3};  list<byte[]> b = new list<byte[]>();   (int u=0; u<4; u++)  {      byte[] inter_byte= new byte[5];      (int p=0; p<5; p++)      {          inter_byte[p] = a[(5*u) + p];      }      b.add(inter_byte);  }

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
