Error is coming how can I solve?

Cell contents reference from a non-cell array object.

Error in Mineral_2 (line 12)
line([A(xmaxA) A(xmaxA)], [limh(1) max(A(:,2))], 'color', chrom{1},'Linestyle',':')

Answer 1

Could you post the code? It could be because you used {} instead of () to access the element of an array but its hard to say without seeing the code.

[RS]

h=plot(A(:,1),A(:,2));
ymaxA=max(A(:,2));
xmaxA=find(A(:,2)==max(A(:,2)));
xA0=A(A(:,2)==0);
limh=get(gca,'Ylim');
chrom=get(h,'color');
line([A(xmaxA) A(xmaxA)], [limh(1) max(A(:,2))], 'color', chrom(1),'Linestyle',':');

again some error are coming here how can I improve?

Before that line, put these lines:

whos chrom
chrom{1}

Tell us what it says. Then look at this link: http://blogs.mathworks.com/videos/2012/07/03/debugging-in-matlab/

You make chrom a cell array. Somehow it is not one at the moment in your code.

[RS]

h=plot(A(:,1),A(:,2));
ymaxA=max(A(:,2));
xmaxA=find(A(:,2)==max(A(:,2)));
xA0=A(A(:,2)==0);
limh=get(gca,'Ylim');
chrom=get(h,'color');
line([A(xmaxA) A(xmaxA)], [limh(1) max(A(:,2))], 'color', chrom(1),'Linestyle',':');

some error are coming here how can I improve?

[Walter Roberson]

plot() of a single column will return the handle of a single lineseries object. You get() the color property of that one object, and what will be returned will be a string rather than a cell array of strings. So just pass chrom into line() rather than passing chrom{1} or chrom(1)

[RS]

A=[];
A(:,1)=B(:,1);
A(:,2)=B(:,2);
figure;
h=plot(A(:,1),A(:,2));
ymaxA=max(A(:,2));
xmaxA=find(A(:,2)==max(A(:,2)));
xA0=A(A(:,2)==0);
limh=get(gca,'Ylim');
chrom=get(h,'color');
line([A(xmaxA) A(xmaxA)], [limh(1) max(A(:,2))], chrom,'Linestyle',':');

Vectors must be the same lengths. This error is coming when I am using this

line([A(xmaxA) A(xmaxA)], [limh(1) max(A(:,2))], chrom,'Linestyle',':');

How can I solve?

You need to have the same number of x values as y values, and you need, need, need to learn basic debugging skills. Is B an integer array, so that you might have multiple locations for xmaxA? What can you learn from doing this:

xValues = [A(xmaxA) A(xmaxA)]
size(xValues)
yValues = [limh(1) max(A(:,2))]
size(yValues)

[Walter Roberson]

You still need the keyword 'color'

line([A(xmaxA) A(xmaxA)], [limh(1) max(A(:,2))], 'color', chrom,'Linestyle',':');
