One common operation is to check if a struct field exists. We can do this using the "isfield" function. The syntax for using this function is as follows: isfield(structVariable, 'fieldName') The function will return a logical value, true if the field exists, and false otherwise. For ...

% ‘none’, then no compositing is performed. Otherwise, if the input image % is indexed, BG should be an integer in the range [1,P] where P is the % colormap length. If the input image is grayscale, BG should be an % integer in the range [0,1]. If the input image is RGB...
MATLAB does not check the validity of MATLAB data structures created in C/C++ or Fortran using one of the Matrix Library create functions (for example,mxCreateStructArray). Using invalid syntax to create a MATLAB data structure can result in unexpected behavior in your C/C++ or Fortran program...

Boolean indicating whether version numbers (_1, _2, etc) will automatically get appended to the filename if the destination file already exists. Default: false. filename: filename at which the data was saved. Save data returned by Titta.collectSessionData() directly to mat file at the ...
save(filename) saves all variables from the current workspace in a binary MATLAB® file (MAT-file) named filename. If filename exists, save overwrites the file. example save(filename,variables) saves only the variables or fields of a structure array specified by variables. example save(file...
