Data Types: single | double | char | string | cell MinThreshold— Lower bound for nonzero values -Inf (default) | real scalar Lower bound for nonzero values, specified as a real scalar. The function sets those elements of p such that 10 log10(p) ≤ 'MinThreshold' to zero. Specify ...
The special filename ‘-’ may be used to return the content of the variables as a string. If no variable names are listed, Octave saves all the variables in the current scope. Otherwise, full variable names or pattern syntax can be used to specify the variables to save. If the -struct...
