I am performing Block convolution method in Matlab. I am planning to use this in the future for my main project as well. Currently the entire code takes 20-40 s to complete the execution. But, sometimes for certain inputs the Matlab doesn’t execute the complete m script and waits infinitely. I have to later kill the task or use Ctrl break. But, if re run the same code without changing the inputs, the code executes properly. What might be the problem of the cause?

I have a project whose time elapsed component is not acceptable as in this project there are several future activities which are either started or already complete. I also have doubt about tasks which are interrupted. How to consider all these and report percentage completion of entire project? I have base lined the project and I am little confused about the measurement. What are fixed duration tasks and how are they different from normal tasks? What are the changes to be done while measuring the performance of whole project?

I have a code which read an input image and searches for a Arrow mark. I need to find the Pin point section of the arrow mark? How to search for the Arrow mark shape in the image? How to find the X,Y vectors of the pixel which is the closest point of the arrow tip? How to locate multiple arrow marks if possible? The arrow marks are single lines only with the inverted V making the tip. The line will be drawn by another user and will be shred to me.

How to create buttons in Matlab. Basically, looking for code to generate Graphical user Interface code. I also have the requirement that if the user clicks on one button in one figure, the button click action should also trigger the corresponding call back function. I have four figures in Matlab and user may select any button in any of the window. Once input is received from the user, the code has to perform similar click functions in remaining windows too. Please help.

I have bought a new laptop and I would like to transfer all old files in the old laptop to the new laptop. What is the best and easiest way to do it? I do not have a portable hard disk and I do not want to buy only for this reason. The file size is around 400 GB I guess. The old system has windows 7 and the new has Windows 8.1 for you information if it helps. I have heard we can connect via USB or Ethernet but don’t know both the methods; type of cables required...

I am trying to solve a equation in Matlab. For example, assume solving quadratic equations. The problem I am facing is the results are not matching on different machines. I had stored a big file with the solutions and when run on my team members PC it gave slightly different results. Though the error is very negligible, the system cannot accept them because they are simply different. One is on Mac and another is on Windows 7. What are the known accuracy issues in Matlab? Can I post the code so that the code can also be verified? How...

I want to block many applications in the windows 7 run PC in home. I have to do this because, I have limited data usage and things such as automatic updated of third party applications shouldn’t consume any data. Also, I have installed many handy tools which loads the ads from the internet. I think, if the application is able to load ads, it can also send a few details to third party. Hence I decided to block all unwanted applications. Kindly suggest me on how to block all software which I have installed from internet access?

I want to detect the custom packet with signature. How to detect the packets? How to extract the packet data body so that I can verify the encrypted signature in the packet. Then I will have to give Full permission for one of my data in the server. What applications are there to perform the said activity already? If I have to automate this, which is the best approach? How to start with networking programming? I know the basics and your kind support towards this will help me in completing this objective.

I want code for running Matlab scripts so that whenever the data is submitted by the user, the code has to pick random numbers from it and generate requested number of 3x4 matrices. The user will provide path of the file in which random numbers are stored. The user will also mention the number of matrices. How to load and randomize the existing numbers in the file? What are the features of file load functions which can accomplish this task? What are the existing random number generation logics?

I am looking for innovative way of adding the third number to the xls sheet in Matlab. I have multiple xls sheets with three columns filled with numbers. It represents some set and presently I want to run through all the sheets and perform the following: I want to check the third column value with the third column value of previous row, if it is less than the average of previous three. I also have to change the colors of the modified cells? Can anybody share the flow of the code? Are there any easy functions for them?
