MATLAB is a numerical computing environment and proprietary fourth-generation programming language. MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages, including C, C++, Java, Fortran and Python. Although MATLAB is intended primarily for numerical computing, an optional toolbox uses the MuPAD symbolic engine, allowing access to symbolic computing capabilities. An additional package, Simulink, adds graphical multi-domain simulation and model-based design for dynamic and embedded systems.

I would like to read the first value which is the timestamp and the values placed at positions 6 and 7. The message type is String and I'm not able to correctly parse the output of this node.

I created the subscription block in Simulink and then I added the BUS Selector with three outputs:

I am trying to use Matlab 2016 as a neural network. I have large amounts of comma-delimited ASCII data that I would like to analyze. Each row of data contains about 1500 elements of alphanumerics. There would be about 100 records/rows of 1500 elements each. The first task I need to do is determine the correlation, if any, between the various elements. I think that would be a clustering issue. Is it practical, or advised, to try to run the entire block of data at one time, or to pick out what I think are the relevant factors and just analyze those for correlations? I have reasonably powerful computing equipment and I don't know if time factors would make looking at the entire data set prohibitive. Once I determined which way to do that, and have figured out some of the correlations, I would then have to set up an actual neural network to try to get some insight into larger blocks of that same type of data.

Any help will be appreciated and points awarded. Thanks.

(i) Develop an algorithm to determine whether a graph represented by a node-node incidence matrix is connected or not. Provide a clear algorithm statement.
(ii) Code your algorithm in any programming language you prefer, run your code on the node-node adjacency matrices. The matrix is 300x300. Also, I need to report my results along with the computation time in seconds

I am very new to image processing and Matlab. I am working with RGB image and used SLIC algorithm to generate superpixel for an image. By using regionprops to calculate the superpixel properties.

[Rcounts binlocations]=imhist(ImageRED);
[Gcounts binlocations]=imhist(ImageGREEN);
[Bcounts binlocations]=imhist(ImageBLUE);
Q1: I have 48 superpixels with Counts(R,G,B channels) it is giving me 256*1 double(most of them are zero). Can anybody explain how to refine them to get each superpixel histogram?

Q2: How can I compare and calculate the distance between two specific superpixel histograms?

Any help is greatly appreciated. Thanks in advance

how i can apply fuzzy logic for this problem? Or is there any other technique i can use for my problem?

Input : parameter values Output : (1) OLTP , (2) DSS , (3) % of OLTP and % of DSS

I have to classify between 3 classes as OLTP, DSS and mix type. if my input matches with OLTP or DSS type it return crisp class. if it matches with mix type it returns the percentage of OLTP and DSS

Hi, I am beginner in Matlab, need help or advise on how to do this? If i have 2 image in gallery (one basketball image and one badminton image)-Basketball.JPG/Badminton.JPG I created GUI. Then i am able to upload the one of the image. But how do i compare this upload image with the 2images in gallery. So that if uploaded image matches Basketball, it will display Basketball. and if uploaded image matches Badminton,it will display Badminton.

in the following code I'm searching for a match of indexes between 2 files , if I found a match take -6,6 elements from the 1st file .

I need to save the found data as (1,13) . (data ) array shows the elements as I print it when I run the code but after finishing executing only the last element is saved .

earFilename = 'EAR_v1.txt';stateFilename = 'output_close_tags_video_1.txt';% read EAR values earfile = fopen(earFilename,'r'); formatSpec = '%d %f %f'; sizeA = [3 Inf];earVector = fscanf(earfile, formatSpec, sizeA);earVector = earVector';% read state file statefile = fopen(stateFilename,'r'); formatSpec = '%d %*s'; sizeA = [1 Inf]; stateVector = fscanf(statefile, formatSpec,sizeA); stateVector = stateVector';% create a dataset containing framenumber, EAR, statedataset = [earVector, -1*ones(size(earVector,1),1)];% for each positive state, +-6 frame are marked as positivedata=[];for i = stateVector' rowNumber = find(dataset==i); for j = -6:6 data=(rowNumber+j); disp(data)

I am using MATLAB 2009,I have a micro-structure image and I transformed into greyscale image and then to BW. Now I want to know the number of pixels along the scale bar (scale bar width is one pixel size), in order to calculate grain size. Please help me to find out How many pixels in the line of specified length with constant width of pixel size. using MATLAB. or suggest me other way to find the grain size from the microstructure image.
Thank you in Advance.
