How could i input this vector phi in simulink, to see the graphic in a scope? Consider the time vector for each point of the phi vector .
phi = [15.4618463574325;17.9320433091703;20.1277739329371;22.1862713927186;24.5192351804709;25.6171004923543;26.4404994762669;26.5777326402523;25.6171004923543;23.9703025245292;22.1862713927186;18.6182091290974;16.8341779972868;15.4618463574325;13.8150483896074;11.3448514378696;9.97251979801534;7.77678917424846;5.71829171446701;3.38532792671470;1.73852995888955;-0.0455011729210426;-1.82953230473163;-3.88802976451308;-5.67206089632366;-6.63269304422167;-7.04439253617796;-5.80929406030910;-3.75079660052764;-1.14336648480448;1.60129679490412;3.79702741867099;6.12999120642331;8.87465448613190;10.5214524539571;11.2076182738842;10.5214524539571;8.05125550221932;5.85552487845244;4.48319323859814;1.87576312287498;0.228965155049821;-0.731666992848187;-0.731666992848187;-0.319967500891895;1.05236413896240;2.69916210678756;4.48319323859814;5.58105855048159;6.54169069837960;8.32572183019018;10.2469861259862;11.4820846018551;13.1288825696802;14.3639810455491;15.4618463574325;16.4224785053305;15.8735458493888;14.2267478815637;12.8544162417094;10.9331519459134;7.22785651830674;5.03212589453987;1.87576312287498;0.366198319035249;-1.96676546871706;-3.61356343654222;-5.67206089632366;-7.86779152009054;-9.78905581588656;-11.5730869476971;-13.3571180795077;-12.9454185875514;-11.2986206197263;-9.65182265190113;-7.86779152009054;-6.08376038827995;-4.84866191241109;-4.57419558444022;-5.26036140436738;-6.90715937219253;-8.55395734001769;-8.96565683197398;-8.82842366798855;-8.00502468407597;-6.08376038827995;-4.02526292849851;-2.51569812465878;-1.14336648480448;0.640664647006112;2.28746261483127;4.07149374664186;5.16935905852530;3.93426058265642;0.503431483020677;-2.92739761661507;-5.80929406030910;-11.7103201116826;-13.7688175714640;-14.5922165553766;-14.7294497193620;-13.4943512434932;-11.7103201116826;-10.0635221438574;-8.55395734001769;-6.63269304422167;-3.75079660052764;-0.868900156833622;1.05236413896240;2.56192894280213;4.20872691062728;5.16935905852530;5.58105855048159;5.16935905852530;3.65979425468557;0.915130974976968;-2.10399863270249;-3.75079660052764;-6.22099355226539;-8.27949101204683;-11.1613874557409;-13.9060507354495;-16.3762476871872;-19.3953772948666;-21.8655742466044;-23.6496053784150;-25.4336365102256;-26.6687349860944;-27.3549008060216;-27.3549008060216;-25.9825691661673;-24.4730043623276;-22.9634395584878;-19.9443099508084;-17.4741129990706;-15.6900818672600;-13.0826517515369;-9.51458948791569;-6.49545988023623;-3.75079660052764;-0.182734336906460]';

Use the "From Workspace" block, specify the data as [t', phi'], connect it to a Scope.
But the value in "t" is not incremental, so you might try t=0:10, phi=0:10 first and then fix the value in your "t".

In general for this situation you could use a From Workspace block (in sources library) , where you would assign the input matrix with the first column as your time vector and the second column as your phi vector. So in your MATLAb workspace (command line or in a script) assign
t = [0.0146635397285680;0.10615 ...
phi = [15.4618463574325;17.9320433091703;...
inputSignal = [t phi];
or just assign it directly in the dialog box like this
However you have a problem, which is that your time vector needs to be strictly increasing, and yours occassionally reverses.
You will have to determine why this is and provide a valid (increasing time) to go with you phi vector.

Also I had a little confusion over the dimensions of the t and phi vectors. They should be entered as columns. I hadn't noticed that in your assignment you had put in a transpose at the end.
