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.

@ the cyclist and @Adam, by using the suggestions of both of you, i get the simple code which has almost solved my problem. If possible then please check my edited question and give me suggestion for the remaining part of my question. thanks

Use this instead
formatspace='Pearson correlation coefficient r = %9.5f';
