Hi matlab user, let i have,
x=[1 2 3 4 5 6 7];
y=[1 3 4 6 7 8 9]
scatter(x,y,'*');
r=corr(x.',y.','type','pearson');
A=r;
[rho]=corr(x.',y.','type','spearman');
B=rho;
formatspace='Pearson correlation coefficient r = %d';
str=sprintf(formatspace,A);
annotation('textbox',[.3 .5 .1 .1],'string',str)
After the operation of above code, i get the figure in the attachment. now the problem is how to pass the second text (spearman correlation coefficient rho = %d) to the variable name formatspace. Also i have used %d, which gives me result like (r=9.9124e^-01), how i can get my result like r=0.99124. thanks
thanks

You can use the text command to place text at any (x,y) coordinate you want.
To display values that are stored in variables, you may need to convert them to strings, for example using the sprintf command.
