In new enough versions of MATLAB, inside a function, if you call a function and you then assign to a variable with the same name as the function, and you then use that name, then MATLAB will know that the function is out of scope (because the variable has that name), but it will also have locked-in the idea that the name is a function rather than a variable. The only way I see that error happening in isolation is if. % Train the network using the specified options and training data. Unrecognized function or variable 'seq'.

Why this error occurs when I use antenna toolbox??? matlab unrecognized function or variable substr The table variable is a special type of the local variable that helps to store data must be scalars in MATLAB, or scalar (i.e., single-element) gpuArray variables.All const pointer inputs in C (const double *, etc.) If you had assigned to sum before calling sum as a function, and then you cleared the variable and then tried to use sum as a function, then you would get a related error message. Due to this error my whole work is pending. fDW = (1/(2*pi)) * sqrt((K/H)*((1/m1) + (1/m2))); fDWSquared = fDW * ((1/(2*pi)) * sqrt((K/H)*((1/m1) + (1/m2)))); To verify: did you run whatever .m file that you stored the code in? then you should probably get rid of those statements from your code.
