Integrating Matlab files w/ other languages

MATLAB provides a compiler which can convert .m files into dll or even C code.
MCC is MATLAB to C/C++ compiler. It can compile m-files to executable files with exe or dll extension. Consult the following article:
MATLAB MEX-files
 
Visual Basic can used to call dlls using
Declare Function matfunname Lib "dllname" Alias "matfunnameA"(ByVal/ByRef arg1 As String, ByVal/ByRef arg2 As String,... ) As Stringsyntax.
Moreover with the full version of Matlab available from market contained on two cds, the compiler is also available.

I hope that above explaination will suffice.

Imote2 with Camera setup IMB400 over Ubuntu 9.10/10.04

Imote2 Camera driver for TinyOS is available in contribution directory of  TinyOS 2.x . It goes by the name of  tinyos-2.x-contrib . Its location within is  tinyos-2.x-contrib/intelmote2/apps I am assuming that you have tinyos-2.1.1 installed, this is required to have Camera Driver build. If you dont have it installed... than better have it done by invoking: apt-get install tinyos-2.1.1 From here on to get the driver working,  the procedure is as follows: Browse to opt directory. cd /opt The recommended way to get the source of tinyos-2.x and tinyos-2.x-contribis is through CVS. echo "Getting TinyOS 2.x and TinyOS 2.x-contrib from CVS" echo "Press enter when asked for password." cvs -d:pserver:anonymous@tinyos.cvs.sourceforge.net:/cvsroot/tinyos login cvs -z3 -d:pserver:anonymous@tinyos.cvs.sourceforge.net:/cvsroot/tinyos co -P tinyos-2.x cvs -z3 -d:pserver:anonymous@tinyos.cvs.sourceforge.net:/cvsroot/tinyos co -P tinyos-2.x-contrib --OR--  echo "

Tensorflow - Simplest Gradient Descent using GradientDescentOptimizer

Below is the code to find the minimum possible value of weight (w) such that the outcome of equation is closest to 0, using Gradient Descent method. These weights are multiplied with input (x) to compute cost, thus minimizing it. The equation is below... w 2 - 10 w + 25 ---------------------- (i) i.e. ( w - 5 ) 2 Thus, the coefficients from (i) would be 1, -10 and 25 import numpy as np import tensorflow as tf coefficients = np.array([[ 1 ], [ - 10 ], [ 25 ]]) # try 1, -20, 100 -- line 4 w = tf.Variable([ 0 ], dtype = tf.float32) x = tf.placeholder(tf.float32, [ 3 , 1 ]) cost = (x[ 0 ][ 0 ] * w ** 2 ) + (x[ 1 ][ 0 ] * w) + x[ 2 ][ 0 ] # (w-5)^2 train = tf.train.GradientDescentOptimizer( 0.01 ).minimize(cost) init = tf.global_variables_initializer() with tf.Session() as session: session.run(init) print (session.run(w)) for i in range ( 1000 ): session.run(train, feed_dict = {x:coefficients}) print (session.run(w)) T
