**Calculate t maximums in single vector MATLAB Answers**

Hi, I have an array where the first row is data, and the second row is frequency, I also have a graph of this data versus frequency. I want to find the maximum values of this data, as it spikes at certain frequencies, and the frequency associated with these maximums.... I'm not a programmer but i have to do quite simple thing in Matlab. I hope you can help me with that. I have some sort of data, in column and i need to find local extrema.

**Find local maxima MATLAB findpeaks - MathWorks France**

This MATLAB function evaluates an expression, and executes a group of statements when the expression is true.... This code is generalized to any number of variables, provided that each of them is scalar. If an expression is passed instead of a variable and that expression happens to be the maximum, then the empty string '' will be returned.

**How to use a loop to find a maximum value MATLAB Answers**

I need to find the x- and y- coordinates of local maxima of objects in a microscope image (in this case, balls of fluorescent DNA that manifests as a dots of a few pixels in the image).... So basically I am wanting to take a given data set, [c], run each variable in [c] through a function to produce a second dataset, [q]. If any value of q is negative, I want to get rid of those corresponding entries in [c], run [c] again through the function and get a new set of values in [q].

**How to find local maxima in plot(XY)? MATLAB Answers**

Now find the local minimum and maximum of the expression f. If the point is a local extremum (either minimum or maximum), the first derivative of the expression at that point is equal to zero. To compute the derivative of an expression, use the diff function:... I have a set of signal data and I'd like to find the local maximums. For example, one of the graphs below has two peaks while the other one has more than two.

- What is the most efficient/fastest way to find the circled local minimum below, the lowest minima between two highest peaks? The graph was created by plot(x,y).
- [M,I] = max(___) finds the indices of the maximum values of A and returns them in output vector I, using any of the input arguments in the previous syntaxes. If the maximum value occurs more than once, then max returns the index corresponding to the first occurrence.
