Accessing data from simulink to Matlab workspace

Hi,
I am trying to retrieve my data coming from simulink to plot it and perform some processing on it.
My test example is a 10 MHz /0.5 V discretized sinusoid exported to the workspace (sampling frequncey 80 MHz/100 sample per frame during a 1e-4 sec. simulation.
here the example and the configuration of the blocks - source and export:
when I look to the exported variable "sin"
struct with fields:
time: [81×1 double]
signals: [1×1 struct]
blockName: 'access_data_from_simulink/To Workspace'
I understand 81 as the number of frames
when I look the signals structure
I have
struct with fields:
values: [100×1×81 double]
dimensions: [100 1]
label: ''
I wanted to plot my sinusoid on an time axis from 0 to 1e-4 s. and perform a fft on it and have my dirac frequency at 10 MHz...
I admit the notion of frame for me is not very clear...
I have tried a lot of things but none is working...
an idea ?
thanks for your time
