Having trouble with Gunzip function in Matlab

Hello! Having a bit of a problem unzipping a .gz file with environmental data in MATLAB. I tried converting the file to .txt in R but it results in much of the data not being shown. I've included examples of the code that I've tried below and the errors that I've received. I have a Mac and tried using Terminal as well but that also does not work.

gunzip(/Users/[name]/Documents/MATLAB/filename.nc,outputdir)

Invalid use of operator.

gunzip(Users/minolidias/Documents/MATLAB/filename.nc)

gunzip(Users/[name]/Documents/MATLAB/runoff.filename.nc)

↑

Invalid expression. Check for missing multiplication operator, missing or

unbalanced delimiters, or other syntax error. To construct matrices, use

brackets instead of parentheses.

 gunzip(/Users/[name]/Documents/MATLAB/filename.nc)

gunzip(/Users/[name]/Documents/MATLAB/filename.nc)

↑

Invalid use of operator.

Use quotes —

Uz1 = gunzip('/Users/[name]/Documents/MATLAB/filename.nc','outputdir')
Uz2 = gunzip('Users/minolidias/Documents/MATLAB/filename.nc')

.

From my understanding you are facing problem in unzipping a .gz file with environmental data in MATLAB R2022a. The input to the “gunzip” function must be a character vector, a cell array of character vectors, or a string array. This is the reason your code example seems to error out. You can modify your code examples as follows to run without any errors-

>> gunzip('/Users/[name]/Documents/MATLAB/filename.nc','outputdir') 
>> gunzip('Users/minolidias/Documents/MATLAB/filename.nc') 

You can refer to following MATLAB documentation link for more information-
