What is the best way to force immediate execution of a function that is being used as part of an anoymous function?
stackAnalyer = str2func([@(x) stackAnalyzerFunction(x', struct2str(dbstack), ')'])
where struct2str() is a function that you would have to write that accepts an input struct and outputs a character vector that, when evaluated, builds a struct that had the same contents as the input struct
Thus stackAnalyzer would end up being something like
@(x) stackAnalyzerFunction(x, struct('file', {'/Users/roberson/MATLAB/626/626588/example_fun.m', '/Users/roberson/MATLAB/626/626588/driver.m'}, 'name', {'example_fun', 'driver'}, 'line', {3, 17}))
However, as there are some data structures that cannot be built from static text, in practice what you would have to end up doing instead is having struct2str() be a call to a serialization routine and the generated result would look something like
@(x) stackAnalyzerFunction(x, deserialize('1gSviPKojg1FuITTmVjoYBIgvfDDowCaw-E40IO3PFwEoyO2cJS05a56UVzWcnDp4.AZj.kfzkQGx0Pd-FAkISK8..auXZiGYi0REiXfBc1KnJiGsIJscBt7bPwMEJRle2-OCU9.NPu.7jaQeiCAgeDU37K8mlL74rDanIezyMn5z05-SnzPsAO'))
In view of the alternatives, are you sure this is wise?
To state things more explicitly:
NO, there is no way to have anything similar to @ evaluate an expression at the time the anonymous function is being built, and store the result in a variable attached to the anonymous function, and refer to the variable in the generated anonymous function.
.. Well, I wouldn't rule it out completely, but it is notoriously hard to inject values into an anonymous function. You can use functions() and access the workspace field and {1} that... but storing values into there is tricky.
