I am trying to import a number specified by a cell position from a XYZ1.m file into another XYZ2.m file. the value of the cell in XYZ1.m is 1.0 but when i import it in XYZ2.m it imports it as 1. I want to import as 1.0. What should i do?

In XYZ1.m

i = 1;
Cell position [3 i 3 i] is 1.0

In XYZ2.m I read,

wave_amplitude = dlmread(fid,'',[3 i 3 i]);

then it prints out,

wave_amplitude = 1;

How to make it read as 1.0?

Thank you

fprintf('%.1f', wave_amplitude);

The 1 you are seeing is identical to 1.0, and it is just a matter of how it is displayed.

Hi,

Thank you. When I do g = fprintf('%.1f', wave_amplitude); It displays it as g = 3. How can i make it g = 1.0 ?

Basically, i am want to read files from a folder. So, i use this function

                fileID = strcat('time_series_',num2str(wave_amplitude),'_',num2str(wave_period),'.mat')

The file name is 'time_series_6.0_12.mat'. But the above function generates 'time_series_6_12.mat'. Due to this I am unable to read the file.

Please advise

The output of fprintf() is the number of characters printed. If you want the string use sprintf() instead.

fileID = sprintf('time_series_%.1f_%d.mat', wave_amplitude, wave_period)

Note: if the input might have more digits beyond 1.0 such as 1.25 then it would be necessary to change this code.

Works Perfectly!! Thanks :)
