the best way to import signal from workspace

hello. i need to import a sinewave from matlab workspace. this must be compared with a sawtooth with the use of simscape component comparator. should i use the block 'from workspace' or 'signal from workspace'. what is the default data type of the saved sinewave in matlab workspace? how can i check or find in matlab what kind of data structure and type is a saved signal?

thank you.

in matlab command

t=0:0.1:100
y=sin(t)
ty=[t' y']

in from workspace block set variable name to ty

or you can use from file then

t=0:0.1:100
y=sin(t)
ty=[t; y]
save filename ty

in from file block set file name block to filename

ok. in fact i have used this code

%t=0.02sec %fsampling=100MHz

t=(1:1:2000000)';% Time Samples f=1000;% Input Signal Frequency fs=100000000;% Sampling Frequency x=(0.8*sin(2*pi*f/fs*t));% Generate Sine Wave

sine=[t,x];

but my simulation results are different from the ones i get if i use a sinewave block from simulink library. what am i doing wrong?
