Multivariate Normal Distribution : Error using mvnpdf (line 67)

Hello everyone,

for the analysis of a measurement I'm trying to use the multivariate normal distribution function mvnpdf.

loglik1 = sum(log(w*mvnpdf(all_energy1, mu1, Sigma)));

Error using mvnpdf (line 67)

X and MU must have the same number of columns.

all_energy2 is 1x19640 double and mu2 is 5x1 double. sigma = 1x5 cell . w= 5x1 double .

I'm using Matlab R2020b.

mvnpdf does not accept cell for any parameters.

mvnpdf does not accept a series of different mu with the intention of evaluating X at each of the mu. The provided mu must have the same number of columns as X and must either have one row or else be the same size as X
