How to get mobility from velocity and force

I have a data of velocity (get from accelerometer) and force data (get from hammer). Now, I need to get mobility from them. I already know that mobility=velocity/force. But I don't know how code it. I just begin learning about signal processing for a week.

Get MATLAB projects with source code for your learning and research. I have a background in structural dynamics, not soil mechanics, but this test looks similar enough. You have measurements of acceleration (NOT velocity, unless your accelerometer is doing something it shouldn't) and force in the time domain. You want to get a mobility measurement in the frequency domain. The basic steps you have to follow are: 1) C...

Integral average of y values with respect to x values

I have two vectors (x and y) of the same size with x having more than one value in the y direction. For example, x is [0.02 0.02 0.03 0.03 0.03 0.04 0.04 0.05 0.05 0.05] and y is [0.23 0.40 0.12 0.16 0.09 0.50 0.02 0.33 0.10 0.08]. I want to convert the attached scattered plot of the two vectors to a simple continuous curve, by evaluating the integral average of y values with respect to x values. Take into account that the x vector is already ordered from small to large values. How could I do this?

how to identify the sampling rate of signal with unknown sampling rate

If i have a signal but i do not know the sampling rate , i need to find the power spectrum of the signal , then plot against the frequency 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. Scholars with 100% privacy guaranteed. Get MATLAB projects with source code for your learning and research. Do you know the range of the values in the signal? e.g. minimum and maximum time. If not then you simply don't have enough information to work it out. If you do then it is just a trivial calculation from the min, max and number of samples, assuming it has a constant sample rate. sampleRate = ( maximumVal - minimumVal ) / numVals - 1;

Can anyone help me with fourier series of a signal?

My doubt is can I break the signal in a triangle and a straight line, then calculating fourier series for each. Will this break may affect my answer (magnitude * frequency) 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. Scholars with 100% privacy guaranteed. Get MATLAB projects with source code for your learning and research. If you’re doing a numeric fft , do the Fourier Transform of the entire signal . To do it symbolically, separate it into two segments for each part of the triangle, and add: syms w t f1(t) f2(t) f1(t) = 40*t; f2(t) = 40-40*t; F(w) = int(f1(t)*exp(1i*w*t), t, 0, 0.5) + int(f2(t)*exp(1i*w*t), t, 0.5, 1); F(w) = simplify(F(w), 'steps',20) F(w) = SEE COMPLETE ANSWER CLICK THE LINK https://www.matlabsolutions.com/resources/can-...

How to calculate the correlation coefficient between an array and a matrix?

I have a matrix A and a matrix B, with the same number of rows and a different number of columns. I need to calculate the correlation coefficient between each single columns of the matrix A and all the columns of the matrix B. For each column of A, the partial result will be an array, so I'm thinking to a matrix as final result. Is there a way to do this avoiding the "for" cycle? Which is the most efficient way to do this? Could you suggest me the best syntax? Finally, I have also to do the same with the mean squared error: again, in this second case, is it possible to avoid the "for" cycle? Thanks for your answers.
