This will normalize each column (assuming no NaN, Inf, or complex):

x = [min(a,[],1);max(a,[],1)]
b = bsxfun(@minus,a,x(1,:));
b = bsxfun(@rdivide,b,diff(x,1,1))

surf(x,t,real(u));
hold on
surf(x,t,imag(u));

There are other possibilities, but you need to describe your thinking about what you would like the display to be considering the 2D nature of complex values.
