Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error.
To construct matrices, we need to use brackets instead of parentheses.
Why?

B, f, and V9 need to be passed to meshgrid as three separate arguments, separated by commas:
B=[3.0000 4.0000 5.0000 6.0000 7.0000 8.1000 9.0000 10.0000 11.0000 12.0000 16.0000];
f=[0.0067 0.0077 0.0088 0.0098 0.0109 0.0120 0.0130 0.0141 0.0152 0.0162 0.0173];
V9=[323.7612 321.5724 319.4098 317.2738 315.1648 311.0602 311.0294 309.0038 307.0070 305.0393 232.7858];
% [a b c]=meshgrid(B f V9);
[a b c]=meshgrid(B,f,V9);
