Error encountered with decomposing time series

I am getting an error that says:

Error: File: Untitled.m Line: 2 Column: 47

Incorrect use of '=' operator. To assign a value to a

variable, use '='. To compare values for equality, use '=='.

try to call the function with either

,...,'model','additive') % property-value pairs

or with a variable model

my_model = 'additive';
result = seasonal_decompose(data,my_model);

Your syntax seems to look like some other languages (python?, R?)

Indeed, your posted script is in Python not Matlab.
