[Solved] What is this function in Matlab? [closed]

So I think I’ve figured this one out as well. It would appear that the images are represented as 6 vectors which hold color, texture and position data. So the input of sample image is an Mx6 array which represents an image. The DatabaseImage holds a number of these vector representations function [out]=Compare(SampleImage,DatabaseImage) % //define … Read more

[Solved] Matlab Repeat Value

repmat and repelem are used for repeating the copies of an array. For your case, you can use either of these as: repmat(A,3,1) or repelem(A,3,1) 0 solved Matlab Repeat Value

[Solved] what is the algorithm used to train NN in matlab by default?

RTFM. The first line of the function’s documentation explains: newff Create a feed-forward backpropagation network. Obsoleted in R2010b NNET 7.0. Last used in R2010a NNET 6.0.4. The recommended function is feedforwardnet. … The training function BTF can be any of the backprop training functions such as trainlm, trainbfg, …. The learning function BLF can be … Read more

[Solved] How can I plot these in matlab or R

Your question isn’t 100% clear, but I believe this is what you’re asking for. I’ve used Matlab. len = 1000; a_ = linspace(0, 5, len); b_ = linspace(0, 5, len); x = zeros(len); for a = 1:len for b = 1:len val(1) = (a_(a)^2 * (1-b_(b))) / (a_(a) + b_(b) – a_(a)*b_(b)) + (1-a_(a))*a_(a); val(2) … Read more

[Solved] Error using .* Matrix dimensions must agree?

As your input image I is a color image (RGB), the array I is three-dimensional: width-by-height-by-3, because for each pixel you need three values: red, green and blue. The output of butterhp, however, is always width-by-height, so you are trying to multiply a 2D-array times a 3D-array, which fails of course. Often, processing in grayscale … Read more

[Solved] Implement MATLAB algorithm in Spartan 3E

RS232 is a connection port for things like UART. If you are asking about downloading matlab code into an FPGA, then no. You can create simulink models and include them into your designs at compile time; but this has nothing to do with RS232. solved Implement MATLAB algorithm in Spartan 3E

[Solved] Matlab/Excel/R: Transforming an unbalanced dataset depending on value of column [closed]

A solution in Matlab: A = [1 5; 1 5; 1 6; 2 4; 2 2; 3 8; 3 4]; nMaxDays = max(A(:, 1)); nMaxSamples = max(accumarray(A(:, 1), 1)); mnSamplesMatrix = nan(nMaxSamples, nMaxDays); for (nDay = unique(A(:, 1))’) vnThisDay = A(A(:, 1) == nDay, 2); mnSamplesMatrix(1:numel(vnThisDay), nDay) = vnThisDay; end 0 solved Matlab/Excel/R: Transforming an … Read more

[Solved] In Matlab how do I automatically plot a set of vectors with means and error bars?

use errorbar, for example errorbar(Vector1,Err) plots Vector1 and draws an error bar at each element of Vector1. The error bar is a distance of Err(i) above and below the curve so that each bar is symmetric and 2*E(i) long. Another example: load count.dat; y = mean(count,2); e = std(count,1,2); errorbar(y,e,’xr’) Note, all this was taken … Read more
