I am running into an issue with my .mat file where one of the variable names has a . in it. How do I ignore the variable from my load command? the name of the varibale is sample.proportion. The load command that works is:
A=load('sample.mat', '-regexp','^(?!sample.proportion)...')
Now how do I edit this load command to allow it to ignore any variable with a . in it?eg test.proprotion, data.test, test,example etc

It was produced from another program, using a matlab script. The strange thing is if I double click the file the variables minus the .proportion variable name loads up. But If i use A=load('sample.dat') it fails to parse the variable name

With a sufficiently old MATLAB release you can use this:
https://www.mathworks.com/matlabcentral/fileexchange/42274-loadfixnames-loads-a-mat-file-fixing-invalid-names
See also:
https://www.mathworks.com/matlabcentral/answers/421-how-do-i-access-an-invalid-named-variable-from-an-exported-mat-file-that-matlab-will-not-recognize
or try Octave, which according to some forums I have read is slightly more forgiving when loading MAT-files.
