I am trying to make a boxplot of the data in a matrix of size [925x902] so i dont want the boxplot to make multiple plots of each column/row and instead one single plot of all the data within the matrix
the matrix is called D and i have the statistical package install on MATLAB version R2021a
Any way t plot this as simple boxplot(D) does not work and error messages come up;
Integers can only be combined with integers of the same class, or scalar doubles.
Any ideas

MATLAB will treat each column as a separate data series.
A = rand(10,5);
boxchart(A)
If you want to only have a single boxplot containing all the data, use the colon operator to turn your matrix data into a vector.
figure
boxchart(A(:))
By the way, I'm using boxchart here, which is in base MATLAB, as opposed to boxplot, which requires the Statistics and Machine Learning toolbox. This approach will work with either.

However you extracted A is probably the same thing you need to do to fix the error you are seeing.
load A.mat
boxplot(A(:))
figure
boxchart(A(:))
