MATLAB: How to plot symbolic row matrix in MATLAB

MATLAB

I have a row vector whose elements are all some arbitrary functions of x. How to plot this row vector on y-axis and index of element on x-axis?

   % code
 strain <1x10 sym>

I want to plot this strain.

I am not sure what exactly you want to do. But is it similar to your solution?

strain=([16 52 93 74 57 66 55 88 99 44]) % sym of 1x10 order
plot(strain)

Try:

% Equillateral Strain Rosette Problem
% angle values (A = 0, B = 120; C =60; seems to be standard for a 60 degree
% equilateral triangle)
A = 0;
B = 120;
C = 60;
% Given Angles
ThetaA = deg2rad(A); %radians for A, it always seems to start at 0
ThetaB = deg2rad(B); %in an equillateral triangle seems to be 180-interior angle
ThetaC = deg2rad(C); %seems to be just interior angle
syms strainx strainy strainxy strainA strainB strainC
eq(1) = strainA == (strainx+strainy)/2 + (strainx-strainy)/2*cos(2*ThetaA) + strainxy*sin(2*ThetaA);
eq(2) = strainB == (strainx+strainy)/2 + (strainx-strainy)/2*cos(2*ThetaB) + strainxy*sin(2*ThetaB);
eq(3) = strainC == (strainx+strainy)/2 + (strainx-strainy)/2*cos(2*ThetaC) + strainxy*sin(2*ThetaC);
vars = [strainx, strainy, strainxy];
[strainx, strainy, strainxy] = solve(eq,vars) %Need to solve in terms of strainA strainB and strainC

which gives:

strainx =
 
strainA
 
 
strainy =
 
(2*strainB)/3 - strainA/3 + (2*strainC)/3
 
 
strainxy =
 
-(3^(1/2)*(strainB - strainC))/3

I have a little utility function ("syntax sugar") for such things...

plot(x(iswithin(x,52,54)))

where

>> type iswithin.m
function flg=iswithin(x,lo,hi)
% returns T for values within range of input
% SYNTAX:
%  [log] = iswithin(x,lo,hi)
%      returns T for x between lo and hi values, inclusive
  flg= (x>=lo) & (x<=hi);
