There is no MATLAB function that examines every level of a structure of structures, or nested structure, to determine if a field exists. The 'isfield' function examines only the top level of a nested structure. To determine if a field exists at any other level, ...
check if numbers exist in a structure field. Learn more about structures, isempty, for loop, logic
How can I check if a.table{20} exists or not or empty? Anything that whould give me information of it exsistance? I could not find any function that could have helped so far. Thank you Walter Robersonon 9 Mar 2019 Open in MATLAB Online ...

If a structure or an object, the number of fields and field names To access themxArraystructure, use functions in the C or Fortran Matrix APIs. These functions allow you to create, read, and query information about the MATLAB data in your MEX files. Matrix APIs use themwSizeandmwIndextypes...
Where the atom variable becomes an indexed Matlab struct variable - containing all your molecules attributes like atom names, coordinates and more. Note that you also get the box dimension variable Box_dim holding the box size if such exists. ...
pnow exists as a PLDAPS class in the workspace, but the experiment hasn't started yet, and the provided experiment function has not been called yet. Execute the .run method to actually begin the experiment: p.run pldaps.run pldaps.runwill open the PTB screen and interface with a number...
for the two-argument option foreval, which only evaluates the second input if an error occurs while the first one is executing. To make the code transparent to MATLAB, usetry/catch. The following script puts avaluein the structureS, ifvalueexists, or else sets ...
This structure does not have a field 'rbm'; new fields cannot be added when structure has been read or used. #MATLAB Coder function dbn = randDBN( dims, type ) #codegen %coder.extrinsic('cell'); % dbn.rbm = cell( numel(dims)-1, 1 ); %...
