		<description>Hi all,
i am going to write a FOR loop in matlab and read the address of Images with Imread command.
But i do not know how to write this loop and Imshow them after reading them.
Can any body help me?
Regards, 
Farhang</description>

dtft is just the z transform on the unit circle.....to calculate dtft you can use FREQZ command.....</description>

		<description>@vivek
instead of using inline use equations directly in the solve, something like

U=solve(&#039;(co-r*sin(fi))^2 + x^2 - 2*(co-r*sin(fi))*x + (r*cos(fi))^2 + y^2 - 2*(r*cos(fi))^2*y - l2^2=0&#039;,&#039;x^2 + h^2 + y^2 -2*h*y - l1^2=0&#039;,&#039;x&#039;,&#039;y&#039;)

and also check the syntex of your first equation.</description>

		<description>i am stuck up at a point in some code I am writing. I desprately need someone to tell me what i am doing wrong here. am posting the code below:

eq1=inline(&#039;(co-r*sin(fi))^2 + x^2 - 2*(co-r*sin(fi))*x + (r*cos(fi))^2 + y^2 - 2*(r*cos(fi))^2*y - l2^2&#039;,&#039;x&#039;,&#039;y&#039;)

MATLAB&#039;s MEX-file facility allows user to use C subroutines as MATLAB m-files. It is also possible to use MATLAB as a computational engine for C subroutines.</description>

		<description>@arijit
SIMULINK is an interactive system for the nonlinear simulation of dynamical systems. It is a graphical, mouse-driven program that allows systems to be modelled by drawing a block diagram on the screen. It can handle linear, nonlinear, continuous-time, discrete-time, multivariable, and multirate systems. SIMULINK runs on workstations using X-windows, under MicroSoft Windows on the PC, and on the Macintosh. It takes full advantage of windowing technology, including pull-down windows and mouse interactions. SIMULINK is fully integrated with MATLAB, and, together with MATLAB and the Control System Toolbox, forms a complete control system design and analysis environment.</description>
