How to apply tranparency in some parts of figure

I am try to make a figure using m_map. I want to apply transparency just in "m_gshhs_h", but I can not.

I tried these and it did not work:

a = m_gshhs_h ('patch', [.7 .7 .7], 'edgecolor', 'k'); alpha (a, 0.5)% error

m_gshhs_h ('patch', [.7 .7 .7], 'edgecolor', 'k', 'alpha');% error

m_gshhs_h ('patch', [.7 .7 .7], 'edgecolor', 'k'); Alpha (0.5)% that all figure makes transparency

Please, does anyone have any idea how to help me?

'FaceAlpha', alphaVal

is the property, value pair you want for a patch. I don't know m_map, but

m_gshhs_h ('patch', [.7 .7 .7], 'edgecolor', 'k', 'FaceAlpha', 0.5)

ought to work.
