Why do I get the error «unrecognized function or variable»

Simulink: ramp->trs fnc->scope. Scope: Data history -> ✅Save data to workspace -> Variable name: phi -> Format: Array. Command window: figure(1); subplot(2, 1, 1); plot(phi(:,1),phi(:,2)); unrecognized function or variable 'phi'

Answer 1

Usually you need to use dot indexing to get the variable data.

 plot(out.phi(:, 1), out.phi(:, 2))

Use To Workspace block Save format to Array

 plot(out.phi(:, 1), out.phi(:, 2))
I wrote it, but it gives error «unrecognized field name "phi"

See my answer and use To Workspace block https://in.mathworks.com/matlabcentral/answers/2061362-why-do-i-get-the-error-unrecognized-function-or-variable#answer_1372892
