How to write matlab code for this equation

ASinkc xe-jβz             
 ASinkc de-h(x-d)e-jβz

[Walter Roberson]

A * sin(k * c) * x * e - j * beta * z
A * sin(k * c) * d * e - h * (x-d) * e - j * beta * z

However, I suspect the e- might be an exponential . If so then the forms might be

A * sin(k * c) * x * exp(-j * beta * z)
A * sin(k * c) * d * exp(-h * (x-d)) * exp( -j * beta * z)

Of course there are other possible meanings, such as

A * sin(kc * x) * exp(-j * beta * z)

It would be easier if there had been an image of the formulae available.

Or even asin(kc) for the arcsine function.
