Hello Arif,
To extract a specific cell from a table in MATLAB by reference to another cell's data, you can use logical indexing. For your example, to find the 'Period' when 'StepNum' is 3, here's a sample code:
% Loaded table is assumed to be 'Periodandfrequencies'
% First, find the row where 'StepNum' is 3
row = Periodandfrequencies.StepNum == 3;
% Then, extract the 'Period' from that row
periodValue = Periodandfrequencies.Period(row);
periodDouble = double(periodValue);
Here's a simplified 1 line code that also handles the case where the value for column "StepNum" is a string in single quotes:
periodWhenStepNumIsThree = Periodandfrequencies.Period(strcmp(Periodandfrequencies.StepNum, '3'));
