You have to make the "stuff" on the rhs of the equal sign the same size as
the "stuff" on the lhs, for example:

octave:7> a = rand(4,4)
a =

  0.934775  0.401068  0.974327  0.841767
  0.042087  0.325470  0.656502  0.711730
  0.519402  0.714157  0.855209  0.522446
  0.844893  0.789146  0.167678  0.271139

octave:8> b = rand(4,4)
b =

  0.142786  0.040289  0.152776  0.632984
  0.953375  0.014280  0.766084  0.582438
  0.577141  0.962024  0.637831  0.051329
  0.659995  0.504942  0.606603  0.061225

octave:9> a(a<b) = b(a<b)*10,      ## Multiply by 10 to make it easier to
see what's replaced
a =

  0.93477  0.40107  0.97433  0.84177
  9.53375  0.32547  7.66084  0.71173
  5.77141  9.62024  0.85521  0.52245
  0.84489  0.78915  6.06603  0.27114
