How to define a variable in octave

WebFortunately Octave allows us to automate the sequence of commands using a for loop. A for loop is a programming structure built around some set of statements. The structure always starts with the keyword for and ends with the word end. A simple example of a for loop is the following (this is how it would like if you type the commands into Octave): WebMay 28, 2024 · For example, one could write: [big,small] = maxmin (7,10); After executing, the variable 'big' would store the value '10' and the variable 'small' would store '7'. If fewer than two variables are used to hold the result then fewer outputs are returned. Writing. a = maxmin (13,5) would store 13 in the variable 'a', and would discard the value of 5.
