Reference to non-existent field 'recording'.

This is my code

question_6 = load('recording.mat');

time = question_6.recording.X.Data

and this is what my command window looks like when i run it:

Reference to non-existent field 'recording'.

Error in lab_9_script (line 11)
time = question_6.recording.X.Data
 

I made sure my .mat that i am calling is named like that and they are all in the same folder yet for some reason it says it does not exist?

what shows up for

whos -file recording.mat

Take the semicolon off that line and see what it reports to the command window.

question_6 = load('recording.mat')

[Paola Quintana]

it does not show anything

[Image Analyst]

Try again. If you get to the time line, it will have to get past the load() line, and if you leave off the semicolon it must show something in the command line.

it was saving as something else. I renamed it but in the workspace it was called diffrently. Thank you!

Answer 1

[per isakson]

%%
clearvars
a=1; b=2; X.data = 17;
save( 'recording.mat' );
%%
question_6 = load('recording.mat')

outputs

question_6 = 
  struct with fields:
    X: [1×1 struct]
    a: 1
    b: 2
>>     

Conclusion. There is no field named recording

Try

time = question_6.X.Data
ans =
    17
