trying to avoid repeating code

plot(sparams.frequency_GHz(1),delta(:,1))

plot(sparams.frequency_GHz(41),delta(:,1))

and for this when i try doing the same it does not work , possible to combine ??

plot(sparams.frequency_GHz(:,1),delta(:,2:end), plot_color,'HandleVisibility','off')

Is sparams a table or struct array? How many rows and columns are there for frequency_GHz data? rows and columns for delta?

Ihaveaquest 2022-8-22

struct array

both

Freq 41X16

delta 41x16

What do you want on your y and x axes?

sparams.frequency_GHz = 10*rand(41,16);
delta = rand(41,16);

This one separates the data based on the columns (16 groups)

scatter(sparams.frequency_GHz,delta,'filled')

xlabel('Frequency (GHz')

ylabel('Delta')

This one separates the data based on the rows (41 groups)

scatter(sparams.frequency_GHz',delta','filled')

xlabel('Frequency (GHz')

ylabel('Delta')

Are you saying there are 10 possible frequency values in the 41x16 matrix?

sparams.frequency_GHz = randi(10,41,16);
sparams.frequency_GHz
ans = 41×16
   8     8     1    10     2     6     1     2     5     8     6     6     6     8     8

delta = rand(41,16);

Create logical array when freq equals 1 or 10.

At_one = sparams.frequency_GHz==1;

At_ten = sparams.frequency_GHz==10;

At_one_ten = logical(At_one + At_ten)

At_one_ten = 41×16 logical array
