Create a cell array containing launch dates, spacecraft names, and planets visited. Some cells contain string arrays, and others do not.

C = {2004,"Messenger","Mercury"; ...
     1977,"Voyager 1",["Jupiter","Saturn"]; ...
     2006,"New Horizons","Pluto"}

C=3×3 cell array
    {[2004]}    {["Messenger"   ]}    {["Mercury"]}
    {[1977]}    {["Voyager 1"   ]}    {1x2 string }
    {[2006]}    {["New Horizons"]}    {["Pluto"  ]}

Convert the strings in C to character vectors.

C = convertContainedStringsToChars(C)

C=3×3 cell array
    {[2004]}    {'Messenger'   }    {'Mercury'}
    {[1977]}    {'Voyager 1'   }    {1x2 cell }
    {[2006]}    {'New Horizons'}    {'Pluto'  }

Note that the function converts the string array ["Jupiter","Saturn"] to a cell array of character vectors, contained in cell C(2,3). To access the contents of the cell, use curly brace indexing.

C{2,3}

ans = 1x2 cell
    {'Jupiter'}    {'Saturn'}

Create a structure containing arrays of data, a title, and labels for a plot. Some of the fields contain strings, and others do not.

S.x = linspace(0,2*pi);
S.y = sin(S.x);
S.title = "y = sin(x)";
S.axislabels = ["x (radians)","y"]

S = struct with fields:
             x: [1x100 double]
             y: [1x100 double]
         title: "y = sin(x)"
    axislabels: ["x (radians)"    "y"]

Convert the strings in S.

S = convertContainedStringsToChars(S)

S = struct with fields:
             x: [1x100 double]
             y: [1x100 double]
         title: 'y = sin(x)'
    axislabels: {'x (radians)'  'y'}

Process an arbitrary number of input arrays of different types.

Create an array of doubles, a structure, and a cell array. The structure and cell array contain strings, specified using double quotes.

x = linspace(0,2*pi,8);
S.y = sin(x);
S.title = "y = sin(x)";
C = {{sin(x),"y = sin(x)"},{cos(x),"y = cos(x)"}};

Convert the strings and return all other data unaltered.

[x,S,C] = convertContainedStringsToChars(x,S,C)

x = 1×8

         0    0.8976    1.7952    2.6928    3.5904    4.4880    5.3856    6.2832

S = struct with fields:
        y: [0 0.7818 0.9749 0.4339 -0.4339 -0.9749 -0.7818 -2.4493e-16]
    title: 'y = sin(x)'

C=1×2 cell array
    {1x2 cell}    {1x2 cell}

Display the contents of the cell array contained in the first cell, C(1). The function converts strings that are in nested cells or nested structures to character vectors. Note that character vectors display with single quotes.

C{1}

ans=1×2 cell array
    {1x8 double}    {'y = sin(x)'}
