about two point Boundary Value problem

Numerical integration of the initial value problem

y''+ y'− y = 0 
y(0) = 0

yielded y(1) = 0.741028.

What is the value of y(0) = (0) that would result in y(1) = 1, assuming that y(0) is unchanged?

Not clear what you mean.

Use the symbolic toolbox and dsolve()

The answer comes out as

(exp(x*sqrt(5))-1)*exp(-(1/2*(x-1))*(sqrt(5)+1))/(exp(sqrt(5))-1)

if you simplify it the right way.
