Read about interp2., imresize.
Le A be your 190*40 variable.
B = imresize(A,[190 400]) ;
B(B==0) = NaN ;
pcolor(B')
shading interp
caxis([1 5])

May be i have explained it wrong because i dont want to extrapolate.
the values in colums are in a distance of 10 like 190*1:10:400
And now i want the values of points in between
The value of 40th point is equal to value of 400th point

What I have given does the same. It is interpolation.
But the values i have seen do not match
