Running a t test in Matlab

I am trying to compare two hypothesis models againist oringal data using a t test.

I need to compare n and n1 and then compare n and n2.

n=105 118 139 164 189 214 240 265 290 316 330 348 363 369 373

n1=105.0000 115.0905 126.1507 138.2738 151.5619 166.1270 182.0918 199.5908 218.7715 239.7954 262.8398 288.0987 315.7850 346.1319 379.3952

n2=105.0000 123.4969 143.9590 166.1440 189.6613 213.9824 238.4763 262.4672 285.3071 306.4456 325.4833 342.1960 356.5293 368.5701 378.5053

I tried putting in the following codes: [n,n1,n2]=ttest2 Error using ttest2 (line 71) Requires at least two input arguments

[n,n1,n2]=ttest2(n,n1,n2) Error using ttest2 (line 110) ALPHA must be a scalar between 0 and 1.

I am not sure what I am missing

It looks like you'll need to call it twice, once with each of your models.

[h,p] = ttest2(n,n1)
