x=[1 2 -99 3 4 -99 5 6 -99];
x(x==-99)=NaN;

Answer 2

[Steven Lord]

Consider using the standardizeMissing function. The first example on that documentation page does exactly what you described.

Answer 3

[VBBV]

Data = load('precip.txt'); % use load function
Data(Data == -99) = NaN

Use load function instead of readtable and try with commented line, in your snapshot code

[Stephen23]

Use READMATRIX instead of LOAD.

That fact that LOAD imports a limited set of text files is really for compatilbilty with ancient MATLAB versions.
