Start by running my spline demo. Adapt as needed.

Did you mean Y instead of X? I'm thinking so. If so, try this:
indexes = Y(2:end) > 1.5 * Y(1:end-1);
Y(indexes) = 1.1 * Y(indexes - 1);
If you really meant what you said, then replace Y by X in the first equation:
indexes = X(2:end) > 1.5 * X(1:end-1);
Y(indexes) = 1.1 * Y(indexes - 1);
