Matrix dimensions must agree.

Actual_Diagnosis_Matrix = [zeros(1,10),ones(1,10)];

number_correct= sum(Actual_Diagnosis_Matrix == Diagnosis_Matrix);

Final_percentage_correct=(number_correct/20)*100;

o/p:->

Matrix dimensions must agree.

Error in main (line 362)

number_correct= sum(Actual_Diagnosis_Matrix == Diagnosis_Matrix);

please help me with this problem as soon as possible

The error message means, that Actual_Diagnosis_Matrix and Diagnosis_Matrix have different sizes. Then the == operator cannot compare them.

Check this using the debugger:

dbstop if error

Then run the code again. When Matlab stops at the error:

size(Actual_Diagnosis_Matrix)
size(Diagnosis_Matrix)

thank you sir . Just for you , I point out my mistake and I fix it. There was a problem of matrix dimention. Actually Actual_Diagnosis_Matrix is a [1 20] matrix and Diagnosis_Matrix is [1 10] . that's why the error is happening . thank you so much sir. You are better than our college teachers.
