Use of modalfrf for operating measurements

I need to calculate the FRF for a mechanical system where the exitation has its origin from a gearbox. I generated simulation data while the mechanical systems rotates under operating conditions. I generated data of velocity an acceleration. For my acoustical analysis I need the frequency response function. So I wanted to calculate them by using the function modalfrf. But I am not sure if I can use this function due to the fact that I do not have a hammer or shaker exitation. So is it possible to calculate the FRF with this function or do I need to use another function?

Is 2020a Network-Named User license backwards compatible for older versions

Currently I have the license server with a license file for 2019a installed on my server for network-named users. I would like to upgrade it to a newer 2020a license file. Will the network-named users that are currently using 2019a still be able to continue using their version or will they need to upgrade to 2020a as well? Basically, can I use older versions of Matlab with a newer license file on my license server?

How to number the peaks and troughs of signal ?

Here is my signal where i need to number the peaks and troughs in numbers as 1,2,3,4...

Invert the signal to find valleys. numPoints = 50; x = sort(rand(1, numPoints)); y = rand(1, numPoints); plot(x, y, 'k-', 'LineWidth', 2); grid on; [peakValues, indexesOfPeaks] = findpeaks(y); hold on; peakx = x(indexesOfPeaks); peaky = y(indexesOfPeaks); plot(peakx, peaky, 'r*', 'LineWidth', 2, 'MarkerSize', 10); % Find valleys on inverted signal SEE FULL ANSWER CLICK LINK https://www.matlabsolutions.com/resources/how-to-number-the-peaks-and-tro...

discrete time optimization with non-linear constraints

Hello, I have an optimization problem to solve with non-linear constraints. It is a control theory based discrete time model (which i feel fules out using fmincon) over a time horizon say N seconds. I found a few old posts similar to this, but none I felt had clear answers. I am going nuts trying to find a way to implement it in matlab. Which Matlab tool would be best suited in this case? Thanks, italic EDIT: the system i s continuous, but we analyse it in a discrete time domain. Thus, variables have discrete values. There are n_v entities and each of the entity has each parameter described below: variables: p,v,u; size(p)=size(v)=size(u)=(1,N) vectors Obj. fn: minimize sum(u(1,:)) ANSWER: Matlabsolutions.com provide latest MatLab Homework Help, MatLab Assignment Help for students, engineers and researchers in Multiple Branches like ECE, EEE, CSE, Mechanical, Civil with 100% output.Matlab Code for B.E, B.Tech,M.E,M.Tech, Ph.D. Schol...
