MATLAB’s xcorr method can be used to compute the cross-correlation of 2 time-sequences which are discrete in nature. The main aim of computing cross-correlation is to enable the use of a part of any incoming signal or beam to examine the transient evolution that is being produced by the...
Hi every one I write my own code to calculate the correlation function for two vectors (A and B) which have 3 columns (A1(t),A2(t),A3(t) and B1(t),B2(t),B3(t)).But it takes long time to run. So I want to use Matlab inbuilt functions...

I need to calculate the cross-correlation without losing or adding data, even though they have different sizes. The file with MPEG frames has 89000 frames and H.263 has 17000 frames. Any suggestions on how to do this in python or matlab? What I managed to do was use numpy.correlate with...
I want to calculate Pearson correlation coefficient of "1000_at" with other samples in the given example, How I should do it? I searched relevant questions but getting results for data sets in which only two samples are present. I am new to statistics and programming, please...
I've got two complex signals. Now I am searching for a correlation. The Matlab-functioncorrcoefgives me a complex correlation coefficient (cc). Interpreting it as usual suggests, that the abs of the cc means the characteristics of correlation. The phase must be the phase shift between the s...
You can use thedet()function in R to calculate the determinant of a matrix. If the determinant is zero, the matrix is singular and does not have an inverse. Here’s how you can check for singularity: # Calculate the determinant of the matrixdeterminant<-det(A)# Check if the determinant...

Is there a way to use the matlab window to obtain the values used by SPM to generate plots (contrast of parameter estimates)? I am interested in obtaining the plot values and the standard deviation. Yes, during each plot in SPM several values are stored in workspace ...
