matlab assignin导出指定workspace evalin执行指定workspace 命令

assignin

Assign value to variable in specified workspace

Syntax

assignin(ws, 'var', val)

Description

assignin(ws, 'var', val) assigns the value val to the variable var in the workspace ws. The var input must be the array name only; it cannot contain array indices. If var does not exist in the specified workspace, assignin creates it. ws can have a value of
'base' or 'caller' to denote the MATLAB base workspace or the workspace of the caller function.

The assignin function is particularly useful for these tasks:

Exporting data from a function to the MATLAB workspace

Within a function, changing the value of a variable that is defined in the workspace of the caller function (such as a variable in the function argument list)

evalin

Execute MATLAB expression in specified workspace

Syntax

evalin(ws, expression)

[a1, a2, a3, ...] = evalin(ws, expression)

Description

evalin(ws, expression) executes expression, a string containing any valid MATLAB expression, in the context of the workspace ws. ws can have a value of 'base' or 'caller' to denote the MATLAB base workspace or the workspace of the caller function. You can construct
expression by concatenating substrings and variables inside square brackets:

expression = [string1, int2str(var), string2,...]
