image processing- area of polygon
hey, I have a known closed polygon which represents diffrent pixels on the image. I need to calculate the area of the polygon in Cm. I can use the function 'polyarea' however I get the result in pixels which doesn't help me. I will appreciate any help I can get! thanking you in advance... ... 19 May 2010 12:40

Connecting PMSM block to SimMechanics
Hi ! I want to simulate a linear actuator with the PMSM block and the PM synchronous motor drive block. For the mechanics I want to use the SimMechanics library. The input of the PMSM should be the torque. How can i connect a simMechanics blocks, like the gear box to the PMSM block and the PM synchronous motor drive... 19 May 2010 07:08

Simulink: check signals offset, phase, amplitude
Hi, I have a simulink model for processing some sine signals (continuous model). There are a lot of operations (multiplying, adding, dividing) between these signals that have different offsets, amplitude, phase and so on. What I would like to know is if there is a way (block) to measure the Offset, Amplitude of a... 19 May 2010 07:08

Connecting PMSM block to SimMechanics
Hi ! I want to simulate a linear actuator with Simscape. I am using the PMSM block and the PM synchronous drive block. The input of the PMSM should be the tourque, to use the internal mechanical system. To simulate the mechanics, I thought about using the simMechanics library. But the PMSM (PM synchrounous motor d... 19 May 2010 07:08

Displaying multiple dicom images in gui
Hi there, I am making a matlab gui with dicom images. I am stuck on the problem where I need to display multiple dicom images in a single Axes i.e. multiple images loaded as frames and can be viewed as a slideshow. Like a 'Next' n 'Previous' push buttons or image changing using a the scroller on the mouse. I have t... 19 May 2010 08:13

hessian help!
hi i have to evaluate the Hessian matrix for my Simulink model. I wrote my cost function in such a way that parameters of my Simulink model and NOT the states are the indipendents variables. At the purpose i wrote function costf = aircraft_costf(parameters) % my cost function assignin('caller','CL0',parameter... 19 May 2010 12:40
